What is a biotic factor in an ecosystem?

A biotic factor in an ecosystem refers to any living component that influences the structure and dynamics of the ecosystem. This includes organisms such as plants, animals, fungi, and microorganisms. Biotic factors play crucial roles in various ecological processes, including competition for resources, predator-prey interactions, symbiotic relationships, and nutrient cycling.

For instance, plants contribute to the ecosystem by providing oxygen, food, and habitat for other organisms. Animals contribute through their roles as herbivores, carnivores, or decomposers, all of which affect the populations and health of different species within the ecosystem. Thus, understanding biotic factors is essential for studying ecological balance and species interactions within any habitat.
