Explanation:

In an ecosystem, energy transfer between trophic levels is inefficient. Typically, only about 10 - 20% of the energy from one level is available to the next level. When a giraffe eats leaves from a tree, the energy it incorporates into its own body is a small fraction of the energy in the leaves. This is due to energy being lost as heat during metabolic processes, used for maintenance, and not all parts of the leaves being digestible.

Answer:

C. 5 - 20 percent of the energy in level B
