Name _______________________________ Robinson Date______________________ Biology –Unit 3 Ecology (Part 1) Unit Review 3. Investigate and evaluate the interaction between living organisms and their environment. a. Compare and contrast the characteristics of the world’s major biomes (e.g., deserts, tundra, taiga, grassland, temperate forest, tropical rainforest).

(DOK 2) • Biotic and abiotic factors in an ecosystem (e.g., water, carbon, oxygen, mold, leaves) • Energy flow in ecosystems (e.g., energy pyramids and photosynthetic organisms to herbivores, carnivores, and decomposers) • Roles of beneficial bacteria • Interrelationships of organisms (e.g., cooperation, predation, parasitism, commensalism, symbiosis, and mutualism) 4. Analyze and explain the structures and function of the levels of biological organization. c.

Killer whales feed at the a. 1st & 2nd trophic levels. c. 2nd & 3rd trophic levels. b. 2nd trophic level only. d. 3rd & 4th trophic levels. 23. Refer to the illustration on the right. On the pyramid, animals that feed on plant eaters are no lower than a. level “A.” c. level “C.” b. level “B.” d. level “D.” 24. Refer to the illustration above. How much energy is available to the organisms in level “C”? a. all of the energy in level “A” plus the energy in level “B” b. all of the energy in level “A” minus the energy in level “B” c. 10 percent of the energy in level “B” d. 90 percent of the energy in level “B” 25. a. b. c. d. The diagram on the right represents the decrease in the number of organisms between lower & higher trophic levels. available energy between lower & higher trophic levels. diversity of organisms between lower & higher trophic levels. All of the above 26. Refer to the illustration above. At each trophic level, the energy stored in the organisms in that level is a. about one-tenth of the energy in the level below it. b. about one-tenth of the energy in the level above it. c. 50 percent of the energy in the level below it. d. 100 percent of the energy in the level below it. 27. Because energy diminishes at each successive trophic level, few ecosystems can contain more than a. two trophic levels. c. five trophic levels. b. four trophic levels. d. eight trophic levels. 28. Why must the producing/autotrophic level of the energy pyramid be the largest level of an energy pyramid?(DOK3) 29. Explain how the population size of predators and prey are interconnected, and how significant changes in the size of either group’s population would influence the population size of the other group.

For example, biomes could be broken down into ecosystems, ecosystems into communities, etc. 49. What specific detail was responsible for distinguishing between a community and a population? (DOK 2) 50. Why does this detail result in a community being significantly larger than a population? (DOK 3)
