What distinguishes a biotic factor from an abiotic factor in an ecosystem?

A biotic factor is defined as any living component of an ecosystem, which includes organisms such as plants, animals, fungi, and microorganisms. These living entities interact with one another and form relationships that are essential for the functioning of ecosystems. They play pivotal roles in processes such as predation, competition, symbiosis, and nutrient cycling.

On the other hand, abiotic factors consist of the non-living physical and chemical components of an environment. These include elements like sunlight, temperature, water, soil, air, and minerals. Abiotic factors influence the living conditions for biotic components and can affect their growth, behavior, and survival.

Therefore, the distinction between biotic and abiotic factors lies fundamentally in the presence of life: biotic factors are any living things within the ecosystem, while abiotic factors are the essential non-living elements that provide the physical environment in which biotic factors exist and interact. This interplay is crucial for maintaining the balance and health of an ecosystem.
