Which of the following factors has been shown NOT to increase species diversity? a. Increased foliage height diversity b. Patchiness of resources c. High soil fertility -8. One difference between predation and parasitism is that a parasite feeds on plants and a predator feeds on animals a. b. a predator feeds on one individual most of its life and a parasite feeds on many individuals during its lifetime a parasite always lives inside its host, but a predator lives outside a parasite usually doesn't kill its host, at least not immediately, whereas a predator kills its prey c. d. 9. In laboratory predator-prey systems a. the predator always eliminates the prey species from the community b. both predator and prey can be maintained in the lab if the system is complex enough that the prey has a refuge but it is not perfect both predator and prey can only be maintained if new individuals are periodically added by the experimenter c. d. the prey always escapes into a refuge and the predator starves e none of the above

6) exploitative and inteference

7) patchiness of resource

8) a parasite usually dosn't kill its host at least not immediately whereas the predator kill its prey

9) the predator always eliminates the prey form the community , Predator-prey systems are potentially unstable, as is seen in the lab where predators often extinguish their prey, and then starve.
