Hello class, we are going to learn about the ecosystems in this unit.
00:00:00
So first of all, I want you to answer a question.
00:00:06
And this is the question.
00:00:10
Do all the animals have the same needs?
00:00:12
Looking at these pictures, you have the first picture, two penguins.
00:00:16
And the second picture, a snake.
00:00:22
So what do you think about this?
00:00:26
Do they need the same things?
00:00:30
We can see the penguins are in a very cold place because we can see snow.
00:00:34
And the snake is not in a really cold place so you can see the grass.
00:00:40
So maybe they don't need the same things.
00:00:46
Therefore, we are going to ask, what is an ecosystem?
00:00:51
Well, an ecosystem is made up of all the living things and all the non-living components that function together in one place.
00:00:57
This means, guys, that the ecosystem is made up of all the living things and all the non-living components that function together in one place.
00:01:07
What is this?
00:01:18
The living things, for example, an eagle, a rabbit, a deer, and the non-living components can be air, water, rocks.
00:01:19
And all that comes together to make the mountain and to make the ecosystem with the animals and the rocks and everything.
00:01:34
Otherwise, you can't say it's an ecosystem.
00:01:43
It's a set of things.
00:01:46
So, an ecosystem is made up of a community of living things in a physical environment.
00:01:49
As you see, it's living things in physical environment.
00:01:58
So, what is the physical environment?
00:02:03
The physical environment is made up of non-living things and non-living components.
00:02:06
This is very important, guys, that you understand that the physical environment is not with the animals.
00:02:14
The animals get into the physical environment and then create the ecosystem, as you can see in the book.
00:02:25
So, here we have it very well, which is ecosystem equals living thing plus non-living things in one place.
00:02:32
The ecosystem is made up of living things, as it can be plants, pine, bushes, animals like bird, fish, mammals, and non-living things in physical environment.
00:02:45
Weather, water, type of soil and rocks, light, humidity, etc.
00:03:02
So, then we have here the ecosystem of the ocean, the ecosystem of the mountain, the ecosystem of the desert.
00:03:16
So, type of physical environment, we have terrestrial and aquatic.
00:03:31
In terrestrial, we're going to have the forest ecosystem, the grassland ecosystem, and the desert ecosystem.
00:03:40
And in aquatic environments, we're going to have freshwater ecosystem, rivers and lakes, and saltwater ecosystems, sea and oceans.
00:03:50
There's a very big difference between them and between those two.
00:04:01
So, guys, we have terrestrial and aquatic.
00:04:08
So, in terrestrial, we have three types, and in aquatic, two.
00:04:17
These two are very important to differentiate because one is freshwater and the other is saltwater.
00:04:21
Remember that there are animals that live in the sea that don't live in rivers.
00:04:27
So, you have to remember that.
00:04:31
Living things.
00:04:33
Every ecosystem has a particular fauna and flora.
00:04:38
Do you remember what is a fauna and what is a flora?
00:04:43
Here is a tip.
00:04:47
Flora, for me, it reminds me of flora.
00:04:49
Flora reminds me of flora.
00:04:54
So, I remember that flora refers to all kinds of plants.
00:04:57
And fauna, if you remember, we have a park in Madrid called Faunia.
00:05:02
It's for animals, for example, but fauna is for animals and flora is for plants.
00:05:10
So, an ecosystem.
00:05:19
We have an organism, one type of species, a population that will be of all the species in the same place,
00:05:22
a community that we have all populations in a place.
00:05:33
So, we have here the orange fish, all the orange fishes, and here we have fishes that are orange and also are green.
00:05:39
So, different in the same place.
00:05:48
And then we have the fishes, green fishes, orange fishes, and maybe a shark here.
00:05:51
So, all of these will be the ecosystem.
00:06:02
Here you have a schema, so you can see the difference between ecosystems, living things, physical environment.
00:06:08
I hope it's easier for you to learn it like that.
00:06:20
And here is this picture.
00:06:25
So, you can see the ecosystem population, then it has the community, and then the ecosystem.
00:06:28
Here you can see, guys, in the drawing, that first is the population, then it has the community, and then it has the ecosystem.
00:06:37
If there is no population, there can't be a community, and if there is no community, there can't be an ecosystem.
00:06:54
Everything that is inside is necessary, each of its parts.
00:07:01
Well, guys, this is it for today. I hope it has been useful for you.
00:07:08
And then you can play the games to see if you have understood it well.
