In ecology, the term "biotic" refers to all living components of an ecosystem. This includes plants, animals, fungi, and microorganisms that interact with one another and their environment. Biotic factors influence the structure of ecosystems and their dynamics, as they play roles such as producers, consumers, or decomposers. They interact with abiotic factors (non-living components) such as sunlight, water, and soil, creating complex networks that support life and drive ecological processes.
