Hello, I am Ivan, and I'm going to explain you the ecosystems. 00:00:00
Ecosystems with Ivan and his toy. 00:00:06
An ecosystem consists of many living things living in the same place or organism with one physical environment. 00:00:13
For example, some animals or eating things in one ecosystem, they interrelate, eat each other. 00:00:24
For example, 00:00:32
I'm a hungry crocodile and I want to eat. 00:00:34
I'm a happy dog. 00:00:41
I am a lot of hungry, hungry, hungry. 00:00:44
Oh, what is this? 00:00:51
Oh no! It's a crocodile! I'm going to die! 00:00:56
Ah, duck, you are going to die! 00:01:01
The physical environment of an ecosystem is the part of the ecosystem that is made up of non-living things. 00:01:06
For example, this water and the stones that are behind this water, they are part of the physical environment of that ecosystem. 00:01:16
There are two types of physical environments. 00:01:27
They are aquatic environments and terrestrial environments. 00:01:31
Like you can see here, terrestrial environments are surrounded by land and air. 00:01:37
And like you can see here, aquatic environments are surrounded by water and there are two types, fresh water and salt water, like this. 00:01:43
And the other part of the ecosystem are the living things, such as plants, animals, bacteria, algae, fungi... 00:01:54
Living things of an ecosystem divide into groups. 00:02:08
Fauna, that are animals, and flora, that are plants. 00:02:15
of our environment divide into two species. For example, a crocodile is from a different 00:02:21
species than a duck. This means that the crocodile and the duck can reproduce, because only can 00:02:31
produce the living things that are of the same species. And if there is a lot of organisms, 00:02:43
like a crocodile, that are a lot of crocodiles, they are a population then. If there are more 00:02:56
crocodiles, they are a community. And then, for example, if there are a lot of ducks, 00:03:05
a lot of the raiders and a lot of many animals they form the biosphere of our planet the earth 00:03:11
i'm going to explain you the types of ecosystems 00:03:19
hello i'm the toy of iban i'm going to explain you terrestrial and aquatic ecosystems 00:03:28
A terrestrial ecosystem is like this. 00:03:34
You see, it has a lot of land and it's covered by air. 00:03:38
And it has an animal. 00:03:45
There are three types of terrestrial ecosystems, 00:03:48
like forest, mountain grassland and desert. 00:03:51
Dramatic ecosystems. 00:03:59
Hello, and now I'm going to explain aquatic ecosystems. 00:04:04
Aquatic ecosystems are two types of aquatic ecosystems, there are seawater ecosystems 00:04:11
and freshwater ecosystems. 00:04:19
This is my video of the ecosystems, bye! 00:04:20
