6. Define and give an example of resource partioning.
- The division of environmental resources by coexisting species populations such that a niche of each species differs by one or more significant factors from the niches of all coexisting species populations. Ex. Seven species of Anolis lizards live in close proximity at La Palma in the Dominican Republic.

7. Describe several defense mechanisms to predation in plants.
- Cryptic coloration makes plants harder to find in a environmental background. Aposematic Coloration helps keep predators away by using poisonous chemicals and bright coloration. Bastesian mimicry helps plants seem like a anosmatic coloration plant, but does not have the same protection.

8. Define and give an example of the following animal defenses:
a. Aposematic coloration - The bright coloration of animals with effective physical or chemical defenses that act as a warning to predators.
b. Bastesian mimicry - A type of mimicry in which a harmless species looks like a different species that is poisonous or otherwise harmful to predators.
c. Cryptic coloration - A camoflouge that makes potential prey difficult to spot against its background.
d. Mullerian mimicry - A mutual mimicry by two unpalatable species

9. Define a keystone species and why they are so important to a community?
- A species that makes an unusually strong impact on community structure, an impact that is disproportional large relative to its own abundance. In other words, they stabilize or control the amount of species in it’s region.

10. Define ecological succession?
- Transition in the species composition of a biologically community, often following ecological disturbance of the community; the establishment of a biological community in an area virtually barren of life.
