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 insed populations What is the main selective pressure in this scenano?
Fish population
Drought
insect population
Leg length
