Which term describes the living components that influence an ecosystem, such as energy flow between organisms?

Explanation:
Living components that influence an ecosystem are called biotic factors. These are the organisms—plants, animals, microbes—and the interactions among them that shape how energy moves through the system. Energy enters as sunlight captured by producers, then flows to consumers as organisms eat one another, with decomposers recycling material from dead organisms. The specifics of who’s present and how they interact (predation, competition, symbiosis) determine the pathways and efficiency of energy transfer. Abiotic factors are nonliving things like temperature and sunlight, environmental is a broad term for surroundings, and living systems isn’t the standard term for the living parts of ecosystems.
