how does carbon enter an ecosystem?

Answer 1

Plants take in carbon dioxide. They use it in their photosynthesis process. They made plant materials from CO2 and water (plus required nutrients of course). So let's say our plant was a corn stalk. We grow it, then eat the corn. The CO2 fixed by the plant in the corn has now entered our ecosystem.

Answer 2

All living things contain carbon. Since you can't have an ecosystem without life, in a way it is carbon that makes an ecosystem. The Earth was formed billions of years ago with abundant carbon. The Earth's early atmosphere had WAY more carbon dioxide than it does now. Living processes have gradually removed that carbon dioxide from the atmosphere, sequestering some of it in coal and oil, but most of it in limestone, until now there is almost none left in the atmosphere. Since we started digging up coal and oil and burning it, we have un-sequestered some of that carbon dioxide and put it back into the atmosphere.

Answer 3

How does carbon enter. Well, it doesn't really have to. Carbon is the essential element of all living things.

Answer 4

carbon is a very abundant element and is found in every organic compound. so i would say to have a pre existing ecosystem it would all ready have carbon in it.

Answer 5

Through photosynthesis and respiration, when an animal or plant dies, the carbon dioxide left is trapped and, over millions of years, turns into fossil fuel.

Answer 6

in my biology class in college, we are learning that ALL biological material are carbon based. When animals die, when we exale (CO2) or drive a car (carbon monoxide) some form of carbon is released into the environment

Answer 7

one of the biggest contributors is industry, then burning fossil fuels , burning wood
