Use diagram to answer. The energy pyramid indicates that

A.few owls at the apex result in breeding problems
B. The most efficient consumer level is at the second trophic level
C.The most energy (kj/kg) is available to owls
D. Grasshopper in grain crops reduce crop yield

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

D. Grasshopper in grain crops reduce crop yield.

This is because the grasshopper, which feeds on the grain, grasses, and weeds, has the highest energy content (18,380kj) in the diagram. This means that a significant amount of energy is being taken away by the grasshopper from the producers, reducing the overall productivity of the ecosystem.
