1. describe and give an example of resource partitioning and explain how it can increase species diversity.
2. what is population dynamics? why do most populations live in clumps?
3. describe four variables that govern changes in population size and write an equation showing how they interact.
4. distinguish between r-selected and k-selected species and give an example of each type. define population density and explain why it can affect the size of some but not all populations.
5. what is ecological succession? distinguish between primary ecological succession and secondary ecological succession and give an example of each. explain why succession does not follow a predictable path.
6. define carrying capacity (k) . what two fundamental characteristics reflect (k). what occurs if/when a population exceeds carrying capacity (k). explain why there is a lag time between the overshoot of carrying capacity and the population dieback.
7. describe each of the following species interactions and give an example of each :

(a) interspecific competition
(b) intraspecific competition
(c) predation
(d) territoriality
(e) symbiosis.
