What is an Ecosystem?
An ecosystem is just a community with all its nonliving surroundings. These non-living surroundings are things like rocks, soil, mountains, air, water, and sunlight.
Different communities form different ecosystems depending on the location of the community. In an ecosystem, the plants,animals, and other organisms rely on each other and on the abiotic factors – the soil, water, and nutrients, for example.
Each species in an ecosystem has its own role to play. This role is called a
niche. Your textbook describes a niche as the full range of physical and biological conditions in which an organism lives and the way in which an organism lives. The niche for one species might be to climb trees and eat their fruit, while the niche for another species might be to hunt for small rodents. If the niche of two species is
very similar, they might compete for food or other resources.
Ecosystems are influenced by all the biotic and abiotic factors in the ecosystem. Abiotic factors are the physical or nonliving, factors that shapes and ecosystem. Sunlight and water are examples of abiotic factors. Biotic factors are defined as biological influences on organisms within an ecosystem, by your textbook. Basically biotic factors are all the living organisms in an ecosystem.
