Concepts:
-
What factors shape a climate?
-
Relating various climates to a particular biome
-
What determines the plants that make up a biome?
-
Reasons for loss of biodiversity and how higher biodiversity can contribute to ecosystem
stability.
-
Understanding the effects of various interspecific interactions (competition, predation,
mutualism, etc) on a population in a community.
-
Examples of keystone species effects on an ecosystem
-
The importance of trophic relationships in regards to energy flow and nutrient cycling in
an ecosystem
-
Reasons why ecosystems vary in their productivity
-
Energy efficiency in regards to the trophic structure
-
Common inputs and outputs of energy in producers, consumers, and decomposers.
-
Recognizing what factors determine if an ecosystem is in primary, secondary succession or
if it is an established climax community.
-
How a chemical or pesticide can accumulate in the tissues - particularly for tertiary and
quaternary consumers.
