c) The density of the vegetation affects how much solar radiation a place will receive—the more grassland, the less solar radiation. d) The density of the vegetation affects how much radiation a place will receive— the more tall trees, the less solar radiation. e) The winds of the upper stratosphere can blow solar radiation away from an area before it reaches the land. 2. Which of the following is NOT one of the major biogeochemical cycles? a) hydrogen cycle b) carbon c) hydrological cycle d) nitrogen cycle e) phosphorus cycle 3. The 10% rule of energy conversion efficiency: a) explains why herbivore biomass must exceed that of carnivores. b) suggests that 90% of what an organisms eats is used in cellular respiration or is lost as feces. c) limits the length of food chains. d) explains why big, fierce animals are so rare. e) All of the above are correct. 4. Which of the following statements about an organism’s niche is NOT true? a) It is not always fully exploited. b) It includes the type and amount of food it consumes. c) It may be occupied by two species, as long as they are not competitors. d) It reflects the ways in which the organism utilizes the resources of its environment. e) It encompasses the space it requires. 5. Coevolution: a) can produce an insect with a tongue as long as its body. b) is responsible for all of the beautiful flowers in the world. c) is responsible for all nectar production by plants. d) reveals that both biotic and abiotic resources can serve as selective forces. e) All of the above are correct. Unit 2. Ecosystems and Communities: Organisms and Environments 6. Unlike your cat, termites are able to use wood as their main source of energy. The best explanation for this ability is: a) their digestive systems produce the enzyme cellulase, necessary to digest the cellulose. b) they use the non-cellulose portion of the wood, thus having to eat continuously. c) their digestive systems contain symbiotic bacteria, which produce a cellulose-digesting enzyme. d) they are slow moving and do not need very much energy. e) they have very chitonous teeth capable of masticating the wood into cud, which is digestible.
