• D. Availability of food resources

Answer: (D)

Verified step by step guidance

1. Understand the concept of limiting factors: Limiting factors are environmental conditions that restrict the growth, abundance, or distribution of a population within an ecosystem. These factors can include food availability, habitat space, predation, and environmental conditions.
2. Analyze the options provided: Evaluate each factor to determine whether it can limit wildlife population production. For example, constant environmental conditions may not necessarily limit population growth, while the absence of predators could potentially allow populations to grow unchecked.
3. Focus on the correct answer: Availability of food resources is a critical limiting factor because all organisms require energy to survive, grow, and reproduce. Without sufficient food, populations cannot sustain themselves, leading to reduced growth or even population decline.
4. Relate the concept to ecological principles: Food availability is directly tied to the carrying capacity of an ecosystem, which is the maximum population size that the environment can support based on available resources.
5. Conclude with the importance of food resources: Emphasize that food availability is often the most immediate and impactful factor limiting wildlife populations, as it directly affects survival and reproduction rates.
