What are the different levels of organization in ecology? Which level includes abiotic factors?
Make a list of important biotic and abiotic factors that affect ecosystems.
What is dispersal? What factors affect it?
Explain the difference between distribution and abundance.
How does light affect aquatic environments?
Draw and label a lake in cross-section. Where would phytoplankton be found?
What zones are found in both freshwater and marine ecosystems?
Explain how climate affects biome distribution.
Know the differences between the terrestrial biomes.
Define population. What are the characteristics that are used to describe populations?
Using the mark and recapture method, calculate the size of a population if 50 frogs were captured initially,
50 were captured a day later, and of those 50, 15 were marked from the original capture.
Draw and label a survivorship curve. Explain each curve. Give examples of organisms for each curve.
Draw and label growth curves. Place K on the curve. What is K? What are the two types of growth?
Explain the difference between semelparity and iteroparity. When is each method an advantage over the
other? In other words, when would an organism benefit from semelparity and when would one benefit from
iteroparity?
What is meant by rmax? When does this occur?
Explain the difference between density dependent and density independent limiting factors. What are
some examples of each?
What is K-selection? What is r-selection?
There are three questions that are “asked” when determining life histories. What are they?
What is an ecological footprint?
