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:

The image shows birds in a V-formation, a well-documented behavior where birds use the updraft from the wings of the bird in front to reduce energy expenditure during flight. This is an aerodynamic efficiency adaptation. V-formation is not related to finding mates, and these birds do not form a eusocial society (eusociality requires specialized castes, which these birds do not exhibit).

Answer:

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