1) What is ecology?
2) What are the 5 factors affecting distribution and abundance of organisms?
3) Using an example of west nile virus/locusts/honey bee – identify the factors that allowed this nonnative species to find and establish their home in new geographical locations.

abiotic factor largely controls life in these biomes?
10) The benthos depends on the photic zone – why is this so?
11) What is the thermocline?
12) What happens in spring and fall seasons in a lake?
13) The Neritic zone in the ocean contains the following organisms:
14) The Abyssal zone in the ocean contains the following:
15) Explain what is meant by the term eutrophication? In this context how are red tides caused and what is
its effect on the whole community in the aquatic biome?
16) What are the two types of lakes? Explain how one can change into the other by the process of
CULTURAL EUTROPHICATION.
17) What is the importance of estuaries and wetlands?
18) Are most behaviors nature or nurture or a combination of both? Give an example.
