OBJECTIVES:
2013-2014
Modern Biology Chapter 21-22 pages 397-408 and 414-423.
Ecology 6a, 6d, 6e, & 6f.
A) Be able to discuss and describe examples of predator– prey relationships and how natural
selection has resulted in organisms being shaped and colored as they are. (Pages 399-400)
B) Discuss two types of mimicry and why it is an advantage for some organisms, such as the King
Snake or certain types of wasps and bees. (Page 400)
C) Explain how competitive exclusion, character displacement, and resource partitioning result from
competition. Give an example of each. (Pages 401-403)
D) Describe how primary succession differs from secondary succession. Explain what type of
succession is occurring on Trinity Mountain after the fire of 1999. Describe the stages that will
occur and what the climax community will look like. (Pages 408-410)
E) Be able to describe the nitrogen cycle as it exists in a typical community. (Pages 373-374)
F) Be able to describe the water cycle using a diagram as it exists in a typical community. (371-372)
