A niche is a summary of the organism’s tolerances and requirements, how they interact to define the conditions and resources needed by an individual or species in order to practice its way of life (Begon et al.
The abundance is the number of organisms in an ecosystem. The different biotic components are connected through food and a number of other relations.

the factors that influence where animals graze, rest, and drink, livestock can be redistrib- uted in a predictable and effective manner so that they do not have undesirable effects in grazed watersheds. Animals are adapted to a combination of temperature and humidity that is affected by rainfall. The earth is made of different biotic and abiotic factors like soil, air, living organisms, forest, etc. The activities of these living organisms have profound direct and indirect effects upon growth, structure, reproduction and distribution of plants on the earth.

Factors affecting distribution • Animal are found to occupy all diverse habitats wherever life is possible but the animals found in different regions, different areas and different localities are not identical. They are directly or indirectly affected by the various biotic and abiotic factors of the environment. Lower temperature prevents majority of reptiles from migrating northwards into the temperate areas. They are directly or indirectly affected by the various biotic and abiotic factors of the environment.

Abiotic Factors: Much of the patchiness of abundance and distribution of plant species is determined by abiotic factors. They are of two types: Air, water, heat and rainfall are the four abiotic factors that affect the environment. and their distribution is affected by abiotic.

They live together on this earth.

They are abiotic and biotic components. They are interactive and interrelated directly or indirectly with eachother.
