what is the nitrogen cycle and why is it important class 8
Answers
Answer:what is nitrogen cycle-
The nitrogen cycle is a repeating cycle of processes during which nitrogen moves through both living and non-living things: the atmosphere, soil, water, plants, animals and bacteria. In order to move through the different parts of the cycle, nitrogen must change forms.
Why is nitrogen cycle important?
*Nitrogen cycle helps bring in the inert nitrogen from the air into the biochemical process in plants and then to animals.
*Plants need nitrogen to synthesize chlorophyll and so the nitrogen cycle is absolutely essential for them.
*During the process of ammonification, the bacteria help degrade decomposing animal and plant matter. This helps in naturally cleaning up the environment.
*Due to the nitrogen cycle, nitrates and nitrites are released into the soil which helps in enriching the soil with nutrients needed for cultivation.
*As plants use nitrogen for their biochemical processes, animals obtain the nitrogen and nitrogen compounds from plants. Nitrogen is needed as is an integral part of the cell composition. It is due to the nitrogen cycle that animals are also able to utilize the nitrogen present in the air.
