Question

Describe interdependence of abiotic and biotic components by taking Nitrogen cycle diagrams.

Answer 1

Hint: The Nitrogen Cycle is a biogeochemical process of nitrogen, where atmospheric nitrogen is converted into different forms and then is absorbed by the plants and animals. It involves biotic and abiotic components as nitrogen is the essential component of air.

Complete answer:
All organisms, including human beings, that live within depend on the resources present on earth. These resources include both the living factors known as the biotic components or factors such as food and the non- living factors called the abiotic components such as air, water.
And in return, these factors of environment are affected by the size and the rate of growth of a population.

Nitrogen cycle consists of 5 steps:
> Nitrogen fixation – It is formation of ammonia from nitrogen.
> Nitrification – It is the formation of nitrates from the ammonia.
> Assimilation – it is the incorporation of ammonia and nitrates into biological tissues.
> Ammonification – it is the formation of organic nitrogen compounds to ammonia.
> Denitrification – it is the process of conversion of nitrogen again by nitrates.
Fixation is the first step which makes nitrogen usable by the plants.

Note:
The nitrogen cycle is a biogeochemical process of nitrogen, where nitrogen is converted into different forms and is used by plants and animals for different purposes.
Main interdependence of abiotic and biotic components on each other is due to nitrogen itself as it acts as a part of the air we breathe.
The above diagram also demonstrates clearly the dependence of living and non-living part. Decomposers and animals keep a regulatory check on the nitrogen cycle.
