Consider the following scenario
A drought hits the habitat of a semi-aquatic bird population. All ponds dry up, and fish
populations decline. There are two groups of birds in the population that differ in leg length and diet. Long-legged birds eat fish, while short-legged birds eat insects . The drought has little
effect on insect populations
What is the main selective pressure in this scenario?
(1 point)
○ insect population
fish population
◦ drought
○ leg length
