   2. adaptations that increase the survival of individual organisms.
   3. the number and relative abundances of different species in a particular place.
   4. physical and chemical transformations of energy and materials in the soil, atmosphere, and water. Answer: a

6. The physical setting in which a species lives is its
   1. community.
   2. habitat.
   3. ecosystem.
   4. niche.

7. A proximate hypothesis
   1. explains how an organism has adapted its physiology.
   2. addresses an organism’s response to the environment.
   3. is a hypothesis that has been tested and revised.
