True or False. In this Food Web Pyramid Which type of consumer gets only 10% of the energy stored in plants?HerbivoreCarnivoreOmnivoreSecondary Consumer - 2. Multiple ChoiceIn the energy pyramid here, which organisms have the most energy available?ProducersCarnivoresHerbivoresTop Predator
- 3. Multiple ChoiceIn the energy pyramid below, which organism has the least amount of energy available?ProducersHerbivoresCarnivoresTop Predator
- 4. Multiple ChoiceIn the energy pyramid here, how much of the energy in each level gets lost as heat or used by the organism for survival?80%90%10%20%
- 5. Multiple ChoiceIf there is 1000 Kcal available in the producers in trophic level 1, how much energy is available in the herbivores in trophic level 2?10 Kcal1 Kcal100 Kcal1000 Kcal
- 6. Multiple ChoiceThis diagram shows the amount of energy that moves from one feeding level to another in a food web.Energy PyramidFood WebEcosystemFood Chain
- 7. Multiple ChoiceTrue or False. In this Food Web Pyramid the consumers on each level only get about 10 percent of energy that the plants have stored.TrueFalse
- 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
- 12. Multiple ChoiceThe diagram represents different levels of a marine food pyramid. Between which two levels is the greatest amount of energy transferredR and QS and RT and SU and T
- 13. Multiple ChoiceA food pyramid represent the relative amount of energy in trophic levels. Which of the following correctly shows a food pyramid?ABCD
- 14. Multiple ChoiceIf these organisms were arranged in a food pyramid, which organism would have the least amount of total energy available?coyoteinsectlizardshrub
- 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 ChoiceThe 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
- 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.
- 20. Multiple ChoiceIn this Food Web Pyramid what is the proper name for the organisms above the producer level at the bottom.herbivoresdecomposercarnivoresomnivores
- 21. Multiple ChoiceThe deer, grasshopper, and bird are all examples of which type of consumers on this food pyramid?decomposersomnivorescarnivoreherbivore
