In ecology, which term best describes living components such as producers, consumers, and predators that influence an ecosystem?

In ecology, the living parts that influence an ecosystem are the biotic (or biological) factors. These include producers, consumers, and predators, all of whom interact and affect energy flow, population sizes, and community structure. The term biological factor best fits because it covers all living components that shape how the ecosystem functions. The other options don’t describe the whole living component: chlorophyll is just a pigment used in photosynthesis, diffusion is a transport process, and denitrifying bacteria are a specific organism involved in a particular nutrient cycle, not the broad category of living influences.
