True or False. In this Energy Pyramid the consumers on each level only get about 10 percent of energy that the plants have stored.
True
False
- 8. Multiple ChoiceIn the energy pyramid here, how much of the energy in the producers gets passed to the herbivores?10%20%80%90%
- 9. Multiple ChoiceWhich of this energy roles is always located at the bottom of an energy pyramid?ProducerSecond-Level CarnivoresHerbivores.First-Level Consumers.
- 10. Multiple ChoiceOnly 10 percent of the energy stored in an organism can be passed on to the next trophic level. Of the remaining energy, some is used for the organism’s life processes, and the rest isUsed in reproductionStored as body fatStored as body tissueEliminated as heat
- 11. Multiple ChoiceThe diagram is intended to show relationships in an ecosystem. What do the arrows represent?The direction of population migrationDifferences in dietary habitsProgressively smaller organismsThe direction of the energy flow

shrub
- 15. Multiple ChoiceThe diagram represents a pyramid of energy in an ecosystem. Which level would most likely contain members of the plant kingdom?ABCD
- 16. Multiple ChoiceWhich organism in figure 1 contains the most available energy?plantsmountain lionshawksnone of the above
- 17. Multiple Choice
The diagram represents a model of a energy pyramid. Which statement best describes what happens in this energy 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
- 18. Multiple ChoiceA 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?The birds would not be affected because they are at the top of the pyramidA large omnivore would consume energy at every trophic level, reducing the amount of energy available to each level above the producersA large omnivore would consume energy only at the first two trophic levels and the 3rd and 4th levels would be unaffectedThe omnivore had little affect because the birds would eat the omnivore’s offspring and the omnivore would die off
- 19. Multiple ChoiceAbout 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 given off as heat.It is stored as vitaminsIt is used in reproduction.It is used in protein synthesis.
