  16. Multiple Choice 3. A food chain shows: a. one possible pathway for energy b. many possible pathways for energy c. the amount of energy available to a producer d. the amount of energy available to a consumer

  17. Multiple Choice 1. Decomposers are important to ecosystems because they: a. are at the highest level of the energy pyramid b. change simple compounds into more complex ones c. make nutrients available for producers to reuse d. convert light energy into sugars through photosynthesis

  18. Multiple Choice 2. Which of the following factors in an ecosystem is biotic? a. insects b. soil c. water d. sunlight

  22. Multiple Choice 3. How is a food web model different from a food chain? a. In a web, energy moves from an organism to only one other. b. In a web, energy may move to many organisms from one. c. In a web, an organism gets energy from one source. d. In a web, an organism receives less energy than in a chain.

  23. Multiple Choice 1. When a rabbit population in a meadow cannot grow any larger, it has reached the: a. climax community b. carrying capacity c. limiting factor d. minimum size

  24. Multiple Choice 2. An unusually cold winter causes the squirrel population to decrease. This is an example of temperature as a: a. carrying capacity b. limiting factor c. climax community d. pattern in space
