4. How are density dependent limiting factors different from density independent limiting factors? Give examples of each.

5. Coevolution happens also between parasites and their hosts. Why is this not surprising?

6. Define and give examples of the following: Mutualism, Commensalism, social parasite.

7. What are common strategies predators use to capture prey, and common defenses found in prey?

8. Draw a food web that could occur in your backyard or here at Cerritos. Include all the trophic levels we discussed in class.

9. Why are there fewer members of the upper trophic levels as compared with primary consumers or the producers?

10. What is carrying capacity?


1. How is a genotype different from a phenotype?
2. What name is given to each of the following genotypes: TT Tt tt
3. Which of Mendel's laws discusses the separation of alleles in meiosis?
4. Which of his laws would describe the behavior of human chromosome 2 and 13 during meiosis?
5. In peas, tall is dominant over short. If two plants tall heterozygous plants were crossed, what proportion of the offspring would you expect to be short?
6. In one breed of chickens feather color is black, blue-gray, or white. How is feather color inherited and why do you think so?
