1 00:00:01,260 --> 00:00:03,259 The ecosystem 2 00:00:04,500 --> 00:00:09,859 First, what is an ecosystem? An ecosystem is formed by two groups 3 00:00:10,199 --> 00:00:17,980 The group of living things that is the biocenosis and the group of non-living things that is the biotope 4 00:00:18,760 --> 00:00:20,760 Who integrates an ecosystem? 5 00:00:22,500 --> 00:00:29,500 Elements of the ecosystem the biotic things such as the whale, the shark 6 00:00:31,260 --> 00:00:36,259 and the abiotic things such as the soil and the rocks. 7 00:00:38,439 --> 00:00:43,439 One, what relationship exists between the living things 8 00:00:44,219 --> 00:00:47,219 and non-living things in the sea? 9 00:00:48,719 --> 00:00:53,719 The plants, fish, and other organisms that live in the seas 10 00:00:54,439 --> 00:00:58,439 help to determine the nature. 11 00:01:01,259 --> 00:01:11,260 The marine organisms produce the most of the oxygen that we breathe. 12 00:01:11,260 --> 00:01:20,260 So, what characteristics have the living things? 13 00:01:20,260 --> 00:01:35,260 All guys, there are aquatic plants and they need so much water because when we take out of the water, they dry up. 14 00:01:35,260 --> 00:01:44,769 Fish, they breed with gills and they are vertebrates because they have a backbone. 15 00:01:44,769 --> 00:01:52,769 Mammals, they breathe with lungs and they are vertebrates because they have bones. 16 00:01:52,769 --> 00:02:03,769 Fruit, these are the relationships between the water, floor and the living things in the sea. 17 00:02:03,769 --> 00:02:13,770 Floor is a part of the biotope and it contains all the nutrients that the animals and plants need. 18 00:02:13,770 --> 00:02:18,770 Water. They need to live, obviously. 19 00:02:18,770 --> 00:02:25,770 Four. In the sea live two types of animals. 20 00:02:25,770 --> 00:02:29,770 Plankton is the group of living things that are small. 21 00:02:29,770 --> 00:02:37,770 Nekton is the group of animals that are medium or big. 22 00:02:37,770 --> 00:02:48,770 The plantona and the black nekton is a peton, that is all the animals. 23 00:02:48,770 --> 00:02:58,389 Five, what temperature is in the Pacific Ocean now? 24 00:02:58,389 --> 00:03:07,150 The temperature that is now in the Pacific Ocean is about 26 to 27 degrees. 25 00:03:07,150 --> 00:03:18,969 Due to the pollution, there are many fish in extinction such as the moonfish, the betta 26 00:03:18,969 --> 00:03:24,990 fish and the vaquita marina. 27 00:03:24,990 --> 00:03:33,229 There is a good chain, and it's this, the sard, it's an scavenger and a quaternary consumer. 28 00:03:33,229 --> 00:03:43,509 The sard eats the salmon, and the salmon is a tertiary consumer. 29 00:03:43,509 --> 00:03:53,629 The salmon eats the sardines, there is a primary consumer, and the sardines eat algae that 30 00:03:53,629 --> 00:04:05,069 are producers what good and bad things have done the ocean the human from the oceans good things 31 00:04:05,069 --> 00:04:16,029 the persons that are aware help to the animals and to the nature to to to a moose 32 00:04:16,029 --> 00:04:24,029 such as the pollution, the plastics and the brush. 33 00:04:24,029 --> 00:04:34,029 The marine work is fantastic, but we need so much wood power to save the seas and oceans. 34 00:04:34,029 --> 00:04:53,029 And this is my marine ecosystem, the algae, the corals, the sharks, and thank you. 35 00:04:53,029 --> 00:04:55,029 Fantastic!
