Question

which of the following is an example of a natural factor that can help balance food and territory in populations?
erosion
sunspots
predators
earthquakes

Explanation:

To determine the natural factor balancing food and territory in populations, we analyze each option:

• Erosion: Primarily affects soil and landforms, not directly population dynamics related to food/territory balance.
• Sunspots: Relate to solar activity, with minimal direct impact on population food/territory balance.
• Predators: Regulate prey populations. By controlling prey numbers, predators help balance the availability of food (as prey consume resources) and territory (since fewer prey mean less competition for space and food), which is a key ecological mechanism for population balance.
• Earthquakes: Are geological events that cause destruction, not a factor that helps balance food and territory in a regulatory way for populations.

Answer:

C. predators
