Question

the image shows a group of birds flying in a v - shaped pattern. which statement is best supported by the image? the birds are close together so they have a better chance of finding mates and increasing their reproductive success. the birds are part of a eusocial society so they have a better chance of finding mates and increasing their reproductive success. the birds are aerodynamically efficient so they can use the air around them to reduce the energy used to fly. the birds are part of a eusocial society so they can use the air around them to reduce the energy used to fly.

Explanation:

Birds flying in a V - shaped pattern take advantage of aerodynamics. Each bird flies in the up - wash of the wingtip vortices of the bird in front, reducing drag and energy consumption for flight. Birds flying in V - formation are not primarily doing so for mating purposes. Also, most birds flying in V - shaped patterns are not part of a eusocial society. Eusociality is characterized by complex social structures like in ants, bees, etc., which is not applicable here.

Answer:

The birds are aerodynamically efficient so they can use the air around them to reduce the energy used to fly.
