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 growth (r ) or logistic
growth (K) reproductive stategies. Explain these two
strategies and discuss how they affect the population over
time.
3) Living organisms play an important role in the recylcing of many
elements within an ecosystem. Discuss how various types of
organisms and their geochemical reactions contribute to the
recycling of either carbon or 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.
