Consider da following scenario

Question

A significant decline in fish Population occurs in da habitat of a semi-aquatic birds' population. There r two groups of birds in da population dat differ in leg length n diet. Long-legged Birds eat fish, while shirt legged birds eat insects da insect population remains stale.

Wut is da main selective pressure in dis scenario

A ) Insect population

B ) Bird populations

C ) Leg length

D ) Fish population

Answer 1

The main selective pressure in this scenario is D) Fish population.

The decline in the fish population affects the long-legged birds that rely on fish as their food source, while the short-legged birds that eat insects are not directly impacted by this change. As a result, the reduced availability of food for the long-legged birds creates a selective pressure that may lead to changes in the bird population dynamics based on their leg length and dietary requirements.
