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