most basic level. It includes all the species ranging from 
plants to different microorganisms.

Genetic diversity
It refers to the variations among the genetic resources of the 
organisms. Every individual of a particular species differs 
from each other in their genetic constitution. That is why 
every human looks different from each other. Similarly, there 
are different varieties in the same species of rice, wheat, 
maize, barley, etc.

Every species has a specific role in an ecosystem. They 
capture and store energy and also produce and decompose 
organic matter. The ecosystem supports the services 
without which humans cannot survive.
