Solution:
Nitrogen is important because, it helps us grow crops, and it produces grass for animal. It comes from lightning and is named nitrogen fixation
By which free nitrogen (N2) is extracted from the atmosphere and converted (fixed) into nitrogen compounds which are plant nutrients (fertilizer). In nature, this process is carried out by certain bacteria (present in the root nodules of legumes such as beans and peas), blue-green algae, and the lightning flash.
Thus the Nitrogen form the atmosphere the biotic part to the ecosystem converted into the biotic part.
Well, it's obvious, because without a transport system, cells wouldn't have the nutrients and things they needed!! And waste wouldn't be able to circulate out of cells.
Answer:
The living components of the environment are known as biotic factors
Explanation:
Biotic factors include plants, animals, and micro-organisms. The non-living components of the environment are known as abiotic factors. Abiotic factors include things such as rocks,water,soil,light,rocks etc...

Induced movement or induced motion is an illusion in which people tend look into it moving even it is really not moving.
