1 00:00:00,690 --> 00:00:04,450 Hello, I am Ivan, and I'm going to explain you the ecosystems. 2 00:00:06,190 --> 00:00:11,250 Ecosystems with Ivan and his toy. 3 00:00:13,349 --> 00:00:24,449 An ecosystem consists of many living things living in the same place or organism with one physical environment. 4 00:00:24,449 --> 00:00:32,710 For example, some animals or eating things in one ecosystem, they interrelate, eat each other. 5 00:00:32,850 --> 00:00:33,490 For example, 6 00:00:34,049 --> 00:00:38,950 I'm a hungry crocodile and I want to eat. 7 00:00:41,869 --> 00:00:43,670 I'm a happy dog. 8 00:00:44,750 --> 00:00:48,689 I am a lot of hungry, hungry, hungry. 9 00:00:51,710 --> 00:00:53,210 Oh, what is this? 10 00:00:56,210 --> 00:01:00,810 Oh no! It's a crocodile! I'm going to die! 11 00:01:01,810 --> 00:01:04,409 Ah, duck, you are going to die! 12 00:01:06,129 --> 00:01:16,189 The physical environment of an ecosystem is the part of the ecosystem that is made up of non-living things. 13 00:01:16,189 --> 00:01:26,769 For example, this water and the stones that are behind this water, they are part of the physical environment of that ecosystem. 14 00:01:27,730 --> 00:01:30,810 There are two types of physical environments. 15 00:01:31,750 --> 00:01:35,810 They are aquatic environments and terrestrial environments. 16 00:01:37,370 --> 00:01:43,510 Like you can see here, terrestrial environments are surrounded by land and air. 17 00:01:43,510 --> 00:01:54,689 And like you can see here, aquatic environments are surrounded by water and there are two types, fresh water and salt water, like this. 18 00:01:54,689 --> 00:02:08,689 And the other part of the ecosystem are the living things, such as plants, animals, bacteria, algae, fungi... 19 00:02:08,689 --> 00:02:15,689 Living things of an ecosystem divide into groups. 20 00:02:15,689 --> 00:02:21,689 Fauna, that are animals, and flora, that are plants. 21 00:02:21,689 --> 00:02:31,370 of our environment divide into two species. For example, a crocodile is from a different 22 00:02:31,370 --> 00:02:43,169 species than a duck. This means that the crocodile and the duck can reproduce, because only can 23 00:02:43,169 --> 00:02:56,169 produce the living things that are of the same species. And if there is a lot of organisms, 24 00:02:56,169 --> 00:03:05,169 like a crocodile, that are a lot of crocodiles, they are a population then. If there are more 25 00:03:05,169 --> 00:03:11,169 crocodiles, they are a community. And then, for example, if there are a lot of ducks, 26 00:03:11,169 --> 00:03:19,569 a lot of the raiders and a lot of many animals they form the biosphere of our planet the earth 27 00:03:19,569 --> 00:03:22,930 i'm going to explain you the types of ecosystems 28 00:03:28,449 --> 00:03:34,689 hello i'm the toy of iban i'm going to explain you terrestrial and aquatic ecosystems 29 00:03:34,689 --> 00:03:38,009 A terrestrial ecosystem is like this. 30 00:03:38,650 --> 00:03:44,469 You see, it has a lot of land and it's covered by air. 31 00:03:45,169 --> 00:03:47,729 And it has an animal. 32 00:03:48,669 --> 00:03:51,569 There are three types of terrestrial ecosystems, 33 00:03:51,569 --> 00:03:59,629 like forest, mountain grassland and desert. 34 00:03:59,750 --> 00:04:04,219 Dramatic ecosystems. 35 00:04:04,219 --> 00:04:11,780 Hello, and now I'm going to explain aquatic ecosystems. 36 00:04:11,780 --> 00:04:19,319 Aquatic ecosystems are two types of aquatic ecosystems, there are seawater ecosystems 37 00:04:19,319 --> 00:04:20,319 and freshwater ecosystems. 38 00:04:20,319 --> 00:04:21,319 This is my video of the ecosystems, bye! 39 00:04:21,319 --> 00:04:22,319 Bye people! 40 00:04:22,319 --> 00:04:23,319 Bye bye bye! 41 00:04:23,319 --> 00:04:24,319 Bye! 42 00:04:24,319 --> 00:04:25,319 Bye! 43 00:04:25,319 --> 00:04:26,319 Bye! 44 00:04:26,319 --> 00:04:27,319 Bye! 45 00:04:27,319 --> 00:04:28,319 Bye! 46 00:04:28,319 --> 00:04:39,720 Bye! 47 00:04:39,720 --> 00:04:40,720 Bye! 48 00:04:40,720 --> 00:04:41,720 Bye! 49 00:04:41,720 --> 00:04:42,720 Bye! 50 00:04:42,720 --> 00:04:43,720 Bye! 51 00:04:43,720 --> 00:04:43,800 Thank you.
