First of all, could i point out that the plant will itself be part of the ecosystem.

A plant returns it's carbon in many different ways.

A plant is made up primarily of carbon, and so when it dies, and other organisms feed off of it, those organisms take in carbon and so it gets passed on that way.

A plant's cells also respire, producing carbon dioxide gas (CO2) which can diffuse into the air surrounding the plant (or be used for photosynthesis).

I'm sure there are many more ways though.

Humans are carbon based lifeforms, when we breath in we inhale oxygen (among loads of other random assortments of gases, whilst it is going around our bodies it reacts with us and creates carbon dioxide


in otherwords... Breath out....

Summarize the carbon cycle starting and ending with carbon dioxide in the atmosphere.?

The carbon cycle is a process where carbon is removed and returned to the atmosphere. The ways of returning carbon to the atmosphere are- 1. Respiration 2. Decomposition 3. Combustion Ways of removing carbon- Photosynthesis. The CO2 in the air is taken in by green plants for photosynthesis. The green plants die eventually and is decomposed; decomposition return carbon to the atmosphere. Animals respire and return carbon dioxide to the atmosphere. Decomposers respire as well. Green plants can be used to make fuels, which combust to return carbon dioxide to the air.


Why you need carbon dioxide for photosynthesis-jokes?

The atmosphere didn't literally need the Carbon Dioxide! The main purpose of the Carbon Dioxide is for the plants! Plants needed Carbon Dioxide for their process called photosynthesis to produce their own food and in return they exchange it into Oxygen but for me personally the Carbon Dioxide in our atmosphere is also there to maintain the balance in it.


What might decrease global atmospheric carbon dioxide?

There is no known way that humans can economically remove carbon dioxide from the atmosphere; all we can really do is reduce our emissions of carbon dioxide and slow down the rate at which atmospheric carbon dioxide levels are increasing. The surface waters of the ocean do absorb some carbon dioxide from the atmosphere as atmospheric carbon dioxide level increase, but there is little interchange betwen the warm upper ocean and the deep layers. However over a period of several thousand years, there is sufficient interchange to absorb large volumes of carbon dioxide, allowing the atmospheric concentration to return more or less to normal. Afforestation. Planting trees will remove carbon dioxide from the atmosphere.


Explain how people are adding carbon dioxide to the atmosphere?

There is a natural cycle in which animals add carbon dioxide to the air and plants remove it, thus maintaining a stable concentration of carbon dioxide over a very long period of time. Humans are part of this natural cycle. Since the start of the Industrial Age, humans have been adding additional carbon dioxide to the atmosphere, increasing the proportion by around 35 per cent, from 260-280 parts per million (ppm) to the present 380 ppm. We do this by burning fossil fuels, manufacturing cement and by deforestation. We can reduce our impact on carbon dioxide concentrations by reducing and eventually eliminating our consumption of coal, oil and natural gas, by finding alternative processes for cement manufacture, including the capture and sequestration of gas produced, and by ceasing deforestation - even allowing some forests to return.


Is carbon dioxide a feature of the earth?

Carbon Dioxide can be released into the atmosphere naturally along with other gases during volcanic eruptions and through geological 'vents' in the Earth's surface. It is also given off by all animals (including humans) when they exhale. Trees and plants ABSORB carbon Dioxide and give off oxygen in return. Man produces about 3 to 6% of all carbon dioxide. Nature contributes the rest.

Do plants give humans oxygen?

yes, through photosynthesis Humans, in return, give off carbon dioxide to the plants, which they exhale after breathing the oxygen.

Global warming is happening because?

Earth's atmosphere has a lot of carbon dioxide. When heat from the sun penetrates the atmosphere, the carbon dioxide makes it hard to return back to space. So minimal heat gets reflected. This is what you call the greenhouse effect. The heat gets trapped inside our atmosphere. This is global warming.


What process is breathing carbon dioxide?

Respiration. We breathe in oxygen, and return carbon dioxide to the air.
