What is a biotic factor?

• Non-living chemical and physical parts of the environment

• Living components that affect the population

• Climate conditions

• Soil composition

Answer explanation

A biotic factor refers to living components, such as plants, animals, and microorganisms, that influence the population and ecosystem dynamics. This distinguishes it from abiotic factors, which are non-living elements.
