Answer to Question 1

ANS: B
Many deep water organisms use patterns of bioluminescence for a variety of purposes. They can
attract prey while hiding their own shadow in the darkness. Also, there are organisms that flash
particular patterns in an effort to attract a mate. Information can be found in the section Examples of
Marine Communities.



Answer to Question 2

ANS: D
There is competition for food, light, and space in a community. The competition can be between
individuals in the same population or between different populations. Information can be found in the
section Communities Consist of Interacting Producers, Consumers, and Decomposers
