Answer to Question 1

ANS: C
This community is named the deep scattering layer due to its tendency to reflect sound pulses which
make it appear like a false bottom to people above. The scattering layer itself is comprised of a dense
population of fish, squid, and other vertical migrators. Information can be found in the section
Examples of Marine Communities

Answer to Question 2

ANS: C
A niche includes the relationship to food and predators. It is what the organism is doing or its role in
the community. Information can be found in the section Communities Consist of Interacting
Producers, Consumers, and Decomposers
