What do you mean by biotic and abiotic factors and how do they influence the number of an ecosystem can support?

Answer 1

Abiotic means nonliving things, like rocks, water, air and sand. Biotics are alive:animals, plants, worms, insects, bacteria etc. Ecosystems depend on a base of biotic elements called producers. If the soil isn't good, or there is little water these will not have many numbers which the next level needs to grow. About 10% of the energy in the first level is passed to the second.

If the the producer numbers are low, the next level will be few and if the second level is low, perhaps a third level will not be sustainable. It is possible that only two levels will be able to be maintained if the soil, water, sunlight, etc are not good.

Answer 2

Biotic factors are living organisms in an ecosystem, such as plants and animals, that interact with each other. Abiotic factors are non-living components, like temperature and precipitation, that affect the ecosystem. The combination of both biotic and abiotic factors determines the carrying capacity of an ecosystem, which is the maximum population size that can be sustained in that environment.
