The diagram represents a pyramid of energy in an ecosystem. Which level would most likely contain members of the plant kingdom?

The diagram is intended to show relationships in an ecosystem. What do the arrows represent?

The direction of population migration

Differences in dietary habits

Progressively smaller organisms

The direction of the energy flow

The diagram represents a model of a food pyramid. Which statement best describes what happens in this food pyramid?

More organisms die at higher levels than at lower levels, resulting in less mass at higher levels.

Energy is lost to the environment at each level, so less mass can be supported at each higher level.

When organisms die at higher levels, their remains sink to lower levels, increasing the mass of lower levels.

Organisms decay at each level, and thus less mass can be supported at higher levels

11.

What does a biomass pyramid compare?

the amount of biomass at each trophic level

the amount of energy available at each trophic level

the amount of biomass consumed at each trophic level
