You will have two of the following questions to write on for the free response portion of the test on Monday:
1) Using an example for each, discuss the following ecological concepts:
a) Succession
b) Energy flow between trophic levels
c) Limiting factors
d) Carrying capacity
2) Many populations exhibit the logistic growth curve
a) Describe what is occurring during each phase of the
curve.
b) Discuss THREE factors that might cause fluctuations in
the curve
c) Organisms demonstrate exponential (r) or logistic growth
(K) reproductive strategies. Explain these two
strategies and discuss how they affect population size
over time.
3) Living organisms play an important role in the recycling of many
elements within an ecosystem. Discuss how various types of
organisms and their geochemical reactions contribute to the
recycling of either the carbon or the nitrogen in an ecosystem.
Include in your answer one way in which human activity has an
important impact on the nutrient cycle you have chosen.
4) Describe and give an example of each of the following. Include in
your discussion the selective advantage of each:
a. Pheromones
b. Mimicry
c. Stereotyped
