2. What is the difference between a K selected species and an r selected species?

3. K species population fluctuates at or around the carrying capacity of its environment, while an r species’ success is based on how well it can reproduce

4. Give an example (from any species) of a fixed action pattern.

5. Male stickleback fish, human eyebrow flash, digger wasps checking nest, and geese rolling eggs.
