Question

The selection in a population, subject to a rapidly changing environment with highly fluctuating food sources, is called as

• A. Stabilizing selection
• B. K- selection
• C. R- selection
• D. Disruptive selection

Answer 1

Answer: (C)

R- selection

R- selection was hypothesized to operate in unstable, hostile, unpredictable, fluctuating or short-lived environments. Species subject to intense R- selection would discover new or empty habitats quickly, reproduce rapidly and prolifically. Therefore, the selection of a population, subject to a rapidly changing environment with highly fluctuating food sources, is called as R-selection. So, the correct answer is option C.
