Producers→ primary consumers(herbivores)→ secondary consumers(carnivores)→tertiary consumers(carnivores).
Here, we can see that the all the organism are directly or indirectly dependent on the producers and they are abundant in every food chain.

Biological reserves also known as natural reserves, and plays very important role in protecting genetic diversity.
Biological reserves are multipurpose protected areas with boundaries restricted by laws.
They have various goals; but the main goal of biosphere reserve is to preserve genetic diversity by protecting wild animals as like in their natural areas, and domesticated plant or animal genetic resources and many others goals too.
A terrestrial biosphere reserve consists different zones; zone of core, buffer and transition zone.
A biological reserve that is designed for a single species will also protect other species in the reserve.
