What does a biotic factor in an ecosystem refer to?

A biotic factor in an ecosystem refers to any living component that has an influence on the organisms within that environment. This encompasses interactions that various organisms have with each other, such as predation, competition, symbiosis, and disease. For instance, the presence of predators can control the population of prey species, while mutualistic relationships can enhance survival and reproduction for both species involved.

This understanding helps in recognizing the complex web of life in ecosystems, where each organism can significantly impact the growth, survival, and reproduction of others. By identifying the interactions among organisms as biotic factors, we can better appreciate how ecosystems function, including the balance of different species and the overall health of the environment.
