Which factor is biotic?

Which factor is biotic?

• A. Predators
• B. Soil pH
• C. Sunlight
• D. Temperature

Answer: (A)

Biotic factors are the living parts of an environment that shape how ecosystems function. Predators are living organisms that interact with other organisms by hunting and feeding, which directly affects prey populations, community structure, and energy flow. That living aspect is what makes predators biotic. In contrast, soil pH is a chemical property of the soil, sunlight is energy from the sun, and temperature is a physical condition of the environment. All of these are nonliving, or abiotic, factors.
