Which statements are true regarding an energy pyramid?

An energy pyramid notes that the energy level of the product approaches the level of the dominant source, but is lower than the average background clutter. Again, it notes that the residual energy of the individual which is primary exceeds the secondary level and below the level of the producer.

Explanation:

An energy pyramid reflects how much power is maintained or deposited at each trophic level in an ecosystem, originally from the sun, in the shape of fresh biomass. Approximately 10 percent of the energy is usually passed from one primary producer to another, thereby eliminating a huge proportion of trophic levels. The energy pyramid is a template showing the movement of energy in an ecosystem from one trophic, or feeding, level to the next. The template is a graph comparing at each photosynthetic stage the resources used by species.
