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

The direction of the energy flow

The direction of population migration

Progressively smaller organisms

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

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

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

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

A scientist collected data in a certain field which is shown in the diagram. He observed that these numbers remained stable over a period of time. He then introduced a large omnivore into the ecosystem. Assuming that the large omnivore was placed here by the scientist, which result can best be inferred?

A large omnivore would consume energy at every trophic level, reducing the amount of energy available to each level above the producers

The birds would not be affected because they are at the top of the pyramid

A large omnivore would consume energy only at the first two trophic levels and the 3rd and 4th levels would be unaffected

The omnivore had little affect because the birds would eat the omnivore’s offspring and the omnivore would die off

About 10% of the energy at one trophic level is passed to the next level. What usually happens to the energy that is not passed to the next trophic level or used to carry out life processes?

It is used in protein synthesis.
