Answer

Brief Explanations:

To determine the cause of the kit fox population decline, we analyze each option:

  • Option A: The kit fox is a predator, so an increase in predator habitat (for other predators) would likely increase competition, but the text mentions human encroachment reducing kit fox habitat, not predator habitat. Eliminate A.
  • Option B: The passage states humans changed the Central Valley (kit fox habitat) with urban/cultural use, and Table 1 shows "habitat loss from human encroachment" as a threat. Carrying capacity (max population an environment can support) decreases with habitat loss. This matches.
  • Option C: The text doesn't mention temperature changes affecting the kit fox. Eliminate C.
  • Option D: The kit fox hunts insects, so an increase in insects would likely help, not harm, the kit fox population. Eliminate D.

Answer:

B. a reduction in carrying capacity due to habitat loss
