When determining energy transfer efficiency from a producer, such as Brussels sprouts, and a primary consumer, such as butterfly larvae, the amount of energy contained in a gram of biomass is less for the producer (4.35 kcal/g) than it is for the consumer (5.5 kcal/g).

Which of the following BEST explains this phenomenon?

A

The greater amount of total potential energy in the producer is offset by the greater total biomass found in this trophic level.

B

The loss of energy as matter flows from one level to the other.

C

The gain of energy as matter flows from one level to the other.

D

The larger ratio of fat to carbohydrates found in the consumer compared to the producer.
