what are biotic factors

Biotic factors are living organisms that shape their environment. They are the living components or factors that affect an ecosystem or other organisms living in that ecosystem. Examples of biotic factors include bacteria, plants, animals, and microorganisms. These living organisms interact with each other and with the abiotic factors in an ecosystem, such as water, light, temperature, and soil. Biotic factors and abiotic factors work together to create a unique ecosystem. In contrast, abiotic factors are non-living chemical and physical parts of the environment that also affect living organisms and the functioning of ecosystems. Examples of abiotic factors include water, light, radiation, temperature, humidity, atmosphere, acidity, salinity, precipitation, altitude, minerals, and soil. The interaction between biotic and abiotic factors is critical in an ecosystem.
