Question

which of the following environmental changes is most likely to lead to the extinction of a tree frog population? choose 1 answer: a a small but rapid decrease in the frogs’ primary food source b a large, gradual decrease in the frogs’ primary food source c a large, rapid decrease in the frogs’ primary food source

Explanation:

To determine which environmental change is most likely to lead to the extinction of a tree frog population, we analyze the options:

• Option A: A small but rapid decrease in food source. The "small" decrease means the frogs may still have enough food to survive or adapt, so extinction is less likely.
• Option B: A large, gradual decrease. The "gradual" nature gives the frog population time to adapt (e.g., find alternative food sources, adjust reproduction rates) to the changing food availability, reducing the risk of extinction.
• Option C: A large, rapid decrease. A "large" decrease means a significant loss of the primary food source, and "rapid" means the frogs have little to no time to adapt. This combination would severely impact their ability to survive and reproduce, making extinction highly likely.

Answer:

C. a large, rapid decrease in the frogs’ primary food source
