Which term denotes the factor that limits population growth, size, or distribution?

• A. Carrying Capacity
• B. Limiting Factor
• C. Primary Succession
• D. Pioneer Species

Answer: (B)

Limiting factors are conditions that prevent a population from growing beyond a certain size or range. They can be scarce resources like food, water, or space, or pressures like predators, disease, or harsh climate. These factors determine how large a population can get and where it can survive. Carrying capacity is related but different: it’s the maximum population size the environment can sustain indefinitely given those limiting factors. Primary succession and pioneer species describe how ecosystems rebuild after disturbance, not the factor that limits population growth.
