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?

The main selective pressure in the given scenario will be on the fish population. Thus, the correct option will be D.

What is Selective pressure?

The selective pressure can be defined as an evolutionary force that causes a particular phenotype to be more favorable in certain environmental conditions than other phenotypes. Selective pressures are the considered forces which can drive the evolution through the process of natural selection. Some phenotypes are more favorable than other phenotypes, depending on the external conditions.

Selective pressures can be detrimental or beneficial to certain phenotypes present within a population. The four main types of selection pressures are the biological factors, such as the predation and disease, the availability of resources, the climatic conditions, and the competition between different species.

Therefore, the correct option will be D.
