What is the importance of the carbon and nitrogen cycles to ecosystems?

Carbon and nitrogen sustains the conservation of the ecosystem.

Explanation:

An ecosystem is a community of organisms interacting in their physical environment. The importance of carbon and nitrogen in an ecosystem can not be over emphasized.

Carbon is the basic building block of life, in plant and animal, which makes its way back into the atmosphere by various activities. It is an important element contained by all living organisms. And can easily react with other groups or other carbon molecules.

Nitrogen is a major nutrient found majorly in the atmosphere for biochemical processes which aids plant and animal growth. It is converted to useful form, e.g plants require nitrogen to synthesize chlorophyll. Plants and animals can not exist without nitrogen.

Therefore, carbon and nitrogen ensured that the ecosystem is preserved.
