Question

How do carbon and oxygen cycles go through an ecosystem?

Answer 1

We must know that air is a mixture of gases. The air in the atmosphere is composed of different gases, namely nitrogen, oxygen, argon and other trace gases. Oxygen is freely available in the air and also dissolved in water. It is the second most abundant gas present in the atmosphere and also the most common element of the human body.

Complete answer:
Three steps are involved in oxygen cycle:
All green plants during the process of photosynthesis, release oxygen back into the atmosphere as a by-product.
All aerobic organisms use free oxygen for respiration.
Animals exhale Carbon dioxide back into the atmosphere which is again used by the plants during photosynthesis. Now oxygen is balanced within the atmosphere.
Carbon cycle shows the movement of carbon in elemental and combined states on earth. Diamond and graphite are the elemental forms of carbon and in combined state, it is found as carbonates in minerals and as carbon dioxide gas in the atmosphere.
The major steps involved in carbon cycle:
Carbon present in the atmosphere is absorbed by plants for photosynthesis.
These plants are then consumed by animals and carbon gets bio accumulated into their bodies.
These animals and plants eventually die, and upon decomposing, carbon is released back into the atmosphere.
Some of the carbon that is not released back into the atmosphere eventually becomes fossil fuels.
These fossil fuels are then used for man-made activities, which pumps more carbon back into the atmosphere.

Note:
We must have to know that oxygen plays an essential role in most life forms on earth and also serves as an essential element in biomolecules like proteins and nucleic acids. The leading creators of oxygen are plants by the process of photosynthesis. Photosynthesis is a biological process by which all green plants synthesize their food in the presence of sunlight.
