Use diagram to answer. The transfer of energy to owls would be more efficient if

A. Grasshopper consumed weeds instead of grains
B.owls consumed mice instead of graspers
C.owls consumed grasshoppers instead of mice
D. Grasshoppers moved from grain to alfalfa crops

The diagram shows: an energy pyramid with an owl mice with numbers 2,527kj a grasshopper with the numbers 18,380kj and grain,grasses, and weeds with the number 120,500kj from top down

C. Owls consumed grasshoppers instead of mice

If owls were to consume grasshoppers instead of mice, they would be getting a higher amount of energy from the grasshoppers, as indicated by the energy pyramid. This would make the transfer of energy to owls more efficient.
