Okay, so we are on page 60. Do you remember that we have been talking about the ecosystems, right? 00:00:00
Yesterday we were talking about the terrestrial ones, just like grasslands, the shaded forests, green forests, 00:00:09
tundra, the Mediterranean forests, and that sort of thing. 00:00:17
And also remember the aquatic ecosystem. 00:00:21
We have fresh water and salt water. 00:00:30
The fresh water, remember, were the lakes and the rivers, right? 00:00:33
Remember? 00:00:41
And the salt water was just there. 00:00:43
The oceans and seas, okay? 00:00:45
There are different animals, for example. 00:00:47
We know that whales, sharks, or dolphins live in the ocean, right? 00:00:49
In the rivers, we can find turtles, otters, and guys, salmon, okay? 00:00:58
And we know that animals that we can find in the pollens, like ducks, small fish, round flies, insects. 00:01:03
Also in the lakes, we find lots of snakes, birds, frogs, birds, right? 00:01:13
So it depends on the place that you go. 00:01:19
You will have different flow rate on file there. 00:01:21
Page 60. 00:01:25
It looks difficult, but I think we can do page 60 and 61. 00:01:30
All right. 00:01:35
And yeah, I think we can do page 60 and 61 right. 00:01:36
This is not really difficult. 00:01:44
So, look at here. 00:01:47
All living things in ecosystems interact. 00:01:50
That's something that we know, right? 00:01:53
Okay. 00:01:55
Also, we have different relationships or interactions. 00:02:00
For example, we have symbiotic relationships. 00:02:07
The organisms depend on each other to survive. 00:02:11
For example, if one animal eats plants, right, they help to disperse the seeds and become the stuff. 00:02:16
And the thing is, for example, if there are some bees that go to the flowers and they transport the seeds and the seeds to other places, right, they need each other, all right? 00:02:25
If there are some animals or there are some fungi, bacteria, they decompose the substances and later the producers, the plants, are going to use to defend each other. 00:02:42
So, also we have the competitive relationships. They compete each other to survive. 00:02:57
There are some animals that they share territory, or they compete for water, or that kind of stuff. 00:03:07
For example, if there are some elephants that are so huge, or rhinos, or hypas, that people, 00:03:15
and they share with lions, or any other animals, they share the water, 00:03:22
that interaction is really dangerous, right? 00:03:29
Because there are some elephants that they go on their own, there are some lions waiting to chop them and eat them. 00:03:34
So there are some competitive interactions for the places. 00:03:44
And even there are some species, there are some populations of lions that compete with another lion for the same territory and the same food and the same water. 00:03:48
Do you understand? 00:03:59
Yes. 00:04:00
Right. 00:04:01
Also, in a symbiotic relationship, we have different types, like mutualism, it means that I help you, you help me, right? 00:04:02
commensalism 00:04:14
it means 00:04:18
that 00:04:20
for example 00:04:21
one organism 00:04:24
helps another 00:04:26
and the other is like 00:04:29
ok, I don't have any benefit 00:04:30
but 00:04:32
there is a relation 00:04:33
piratism 00:04:36
one organism 00:04:38
is affected 00:04:42
One has a benefit and the other no. The other is damaged. 00:04:44
For example, like the fleas. The fleas, la pulpa. The fleas, they take your blood. 00:04:51
They give you the blood. They have a benefit and you have a stem. 00:04:57
And you have a pain here. You lose your blood. 00:05:04
So it's not good, right? 00:05:10
No. 00:05:12
Okay, so, in competitive relationship, 00:05:12
we have competition for water, for wood, for light, for space, for everything. 00:05:17
And there are others, there's predation. 00:05:23
There is a predator and a prey. 00:05:26
The predator is the animal that is going to hunt another, 00:05:29
and the prey is the animal who is going to be hunted. 00:05:32
For example, an owl and a mouse. 00:05:35
the owl 00:05:36
needs the mouse 00:05:38
and it's the predator, isn't it? 00:05:39
It's the consumer. It's going to eat 00:05:42
the primary consumer, 00:05:44
the mouse. Do you understand? 00:05:46
And it's for food. 00:05:48
Of course, it's good for the owl because it's going 00:05:50
to obtain energy 00:05:52
but for the mouse it's going to die. 00:05:53
So, that's the problem. 00:05:56
So, we have 00:05:58
relationships. 00:05:59
Alright? 00:06:03
The interaction. We have symbiotic 00:06:04
relationships. Remember, mutualisms, both organisms have a benefit. Comensalisms, one 00:06:06
has a benefit, the other is okay. It doesn't matter. And it's unaffected. It's like the 00:06:17
spider make a web in between plants. It's very good for the spider, and the plant is 00:06:30
Black is infected. Parasitism. There are some insects that bite the dog or the animals and feed the blood. 00:06:36
Of course the dog is infected and can have some problems. 00:06:47
Competitive relationship. Competition happens when two or more organisms need the same resources like water, food, light, space. 00:06:52
And also we have depredation. Depredation is what we said before. We say depredator, then we depredator. Depredator and depredator. Okay? Right. Depredator is the one who has, and the other is the hunter. 00:07:03
Okay, well, so this is easy, so, um, interaction, right? 00:07:21
No, please, have a look. 00:07:31
Interaction. 00:07:34
We have, um, interaction, and, um, interaction. 00:07:36
So, what is this? 00:07:43
Please, be quiet. 00:07:46
Thank you. 00:07:48
What is this? 00:07:48
Symbiotic. Symbiotic. Symbiotic relationship. And? Competitive. Competitive. Competitive relationship. 00:07:49
So, remember, we have mutualism, alright? So, both organisms has a benefit, alright? 00:08:08
to write commensalism doesn't matter if you have to see how do you write it okay 00:08:30
commensalism one is okay the other is the same right it's an effective 00:08:44
I'm part of citizen all right these words are really hard because they are 00:08:53
difficult to pronounce and difficult to write this mutualism commensalism 00:09:07
Parasitism. I think that they are easier to pronounce than writing. Parasitism. Remember, one has a benefit and the other has a problem. 00:09:12
Competitive, we have the competition for, we have the competition for light, water, 00:09:30
space, all that places, and also we have, we have the competition, and what was the 00:09:44
Predator. 00:09:55
Predator. 00:09:56
Predation. 00:09:57
Yes, sometimes I don't know how you pronounce something, but then I will remember it all 00:09:58
right. 00:10:07
Predator. 00:10:08
And the prey. 00:10:09
Okay. 00:10:10
The prey is hunted. 00:10:11
The predator. 00:10:12
Predator. 00:10:13
He is hunted. 00:10:14
Predator. 00:10:15
Predator. 00:10:16
Predator. 00:10:17
Predator. 00:10:18
Predator. 00:10:19
Predator. 00:10:20
Predator. 00:10:21
Predator. 00:10:22
Predator. 00:10:23
Predator. 00:10:24
hands. I'm praying. Remember. Alright. Very good. So. So, so. Copy this if you want. And 00:10:25
we're going to do number two. For number two, we're going to listen to something now. 00:10:39
Okay, so have a look, and we're going too much, okay? 00:10:55
So copy it, please, copy the question, copy everything, write it there, and... 00:10:59
All right, we're going to keep on listening, ready, steady, go. 00:11:04
Which definition describes each relationship? 00:11:16
Listen, then read a much, if you're not going to. 00:11:20
Two. Which definition describes each relationship? 00:11:22
Listen, then read and match in your notebook. 00:11:29
Butterflies feed on nectar produced by flowers. 00:11:34
As butterflies travel from one flower to another, they pollinate the plants. 00:11:40
This means plants can reproduce and the butterflies obtain the food they need 00:11:45
This kind of relationship is called mutualism 00:11:53
because both living things receive benefit from each other 00:11:58
Mosquitoes suck the blood of other animals like cows or sheep 00:12:03
They do this by biting the animal 00:12:10
A mosquito bite can cause irritation and infections in the animals. 00:12:14
This kind of relationship is called parasitism. 00:12:21
This is because the mosquito gets the food it needs, but the animal it takes the food from is harmed. 00:12:26
Some plants have a relationship with other living things called commensalism. 00:12:35
These plants produce spiny seeds that cling to the fur of animals. 00:12:41
The plants use this method of seed dispersal for reproduction. 00:12:48
The seeds do not harm the animal, but the animal doesn't get any benefit from the relationship. 00:12:53
2. Which definition describes each relationship? 00:13:00
Listen, then read and match in your notebook. 00:13:18
Butterflies feed on nectar produced by flowers. 00:13:24
As butterflies travel from one flower to another, they pollinate the plants 00:13:28
This means plants can reproduce and the butterflies obtain the food they need 00:13:35
This kind of relationship is called mutualism 00:13:42
because both living things receive benefit from each other 00:13:47
Mosquitoes suck the blood of other animals like cows or sheep. 00:13:52
They do this by biting the animal. 00:14:01
A mosquito bite can cause irritation and infections in the animals. 00:14:05
This kind of relationship is called parasitism. 00:14:10
This is because the mosquito gets the food it needs, 00:14:15
but the animal it takes the food from is harmed. 00:14:19
Some plants have a relationship with other living things called commensalism. 00:14:24
These plants produce spiny seeds that cling to the fur of animals. 00:14:32
The plants use this method of seed dispersal for reproduction. 00:14:38
The seeds do not harm the animal, but the animal doesn't get any benefit from the relationship. 00:14:42
Okay, well, now. 00:14:55
Commensalism. What do you think is a commensalism? 00:15:00
Receiving without giving. 00:15:06
All right. Parasitism. What do you think? Receiving and harming. See, mutualism. Giving and receiving. All right. Good. 00:15:09
now page 61 page 61 61 remember we're going to do this we're going to copy the 00:15:34
table about 00:15:57
interaction. Complete it with 00:15:59
a key. Alright? That's what we say 00:16:01
here. Vale? 00:16:03
Vale? 00:16:06
Ready, steady, go. 00:16:12
Mosquito. 00:16:20
A human being. The mosquito 00:16:21
fits on our globe. 00:16:23
Blue. Sorry. What do you think? 00:16:25
Mutualism, commensalism, parasitism 00:16:27
or competition. What do you think? 00:16:30
remember the mosquito feeds on our blood one is it's receiving but we are being harming self 00:16:31
we are being harmed 00:16:48
both animals are scavengers and they need the same food so what is this 00:16:49
Mutualism, commensalism, parasitism or competition? 00:17:00
Competition. 00:17:05
Competition. 00:17:06
Tartar and remora. The remora feeds on the tartar's fruit and scrubs. 00:17:07
What do you think? 00:17:13
Remember that the commensalism is receiving but not giving. 00:17:19
Alright. Clownfish and sea anemone. The clownfish cleans the sea and the sea anemone protects the clownfish. 00:17:30
It's mutualism. Alright? Yes or no? 00:17:39
Yes. 00:17:44
You copy all of this? 00:17:57
I don't know what page it is. 00:17:59
Sixty. 00:18:01
Sixty? You don't know that? 00:18:03
Alright, so... 00:18:05
Mosquito, I'm human being... 00:18:11
Mosquito... 00:18:15
I'm human being... 00:18:19
The mosquito fits all over the place. 00:18:34
The mosquito... 00:18:36
The mosquito feeds on our blood. 00:18:38
Alright, and what is this? 00:18:48
What is this called, number one? 00:18:51
What is this called, remember? 00:18:54
This is pa... 00:18:57
Parasitism. 00:19:00
Parasitism. 00:19:02
Par-a-si-ti-sum. 00:19:04
Number two. 00:19:10
Number two. 00:19:12
Hyena and vulture. 00:19:14
Hyena and vulture. 00:19:16
They say both animals are scavengers. 00:19:26
They need the same territory. 00:19:30
Both animals. 00:19:33
or scavengers. So what do you think? 00:19:36
What do you think? Mutualism, Comensalism, 00:19:41
Parasitism, Parasitizen or 00:19:48
Competition. What do you think? 00:19:51
Competition, great because they compete for the same 00:19:56
tools, right? For the same territory. Competition. 00:19:58
Really, really nice. Number three. 00:20:02
Tartar and Remora. Tartar and Remora. 00:20:06
Tartle and Remora. You can copy from here, or you can copy from the blackboard, okay? 00:20:10
Future, copy this! 00:20:21
Yeah, of course. The Remora fits on the Tartles. 00:20:23
The Remora feeds on the turtle's food scraps. 00:20:27
What do you think is this relationship, this interaction? 00:20:52
Commensalism is when one animal receives without giving and another gives without receiving. 00:20:56
all right number four fun fish and sea animals fish fish see they have each other right they 00:21:28
they help each other so this is if they help each other it is new mutualism all right okay 00:21:57
So, we have here, commensalism, commensalism, we have, one organism has a benefit, 00:23:48
And remember, benefits the organism, harms the organism, doesn't affect the organism. 00:25:02
Okay? 00:25:18
So we have one of the organisms. 00:25:19
Competition, what do you think? 00:25:28
Predation, it will be just like how hard they have to each other. 00:25:30
Mutualism, both, both are, both are, have a benefit. 00:25:44
Parasitism, one has a benefit, the other is hard. 00:25:54
Predation, one has a benefit, you understand? 00:25:58
I'll be long with you tomorrow. 00:26:07
