Which term describes the living components of the environment that organisms interact with?

• A. Biotic Factor
• B. Abiotic Factor
• C. Carrying Capacity
• D. Limiting Factors

Answer: (A)

Biotic factors describe the living components of the environment that organisms interact with. This includes plants, animals, microorganisms, and the interactions among them—such as predation, competition, mutualism, and decomposition. These living elements shape how ecosystems function, because they drive processes like energy transfer and nutrient cycling through their interactions. In contrast, abiotic factors are nonliving aspects like temperature, rainfall, light, and soil chemistry. Carrying capacity refers to the maximum population size an environment can support over time given resource limits, not to the living components themselves. Limiting factors are conditions that constrain growth or survival and can be either biotic or abiotic, but the phrase that specifically names the living components is biotic factors.
