A. birth/death rate: These rates are more of a response to limiting factors than a limiting factor themselves.
B. immigration: While immigration can influence population size, it doesn’t inherently limit it.
C. available niche: This relates to the ecological roles that species can occupy, which is important but somewhat indirect as a limiting factor.
D. resource supply: This is the most direct limiting factor, as the availability of resources (like food, water, and habitat) fundamentally determines the carrying capacity of an environment for various species.
