Ecology
Ecosystem
Emigration
Exponential growth
Habitat
Immigration
K-strategist
Limiting factor
Logistic growth
Mutualism
Niche
Parasitism
Population
Population density
Population distribution
Population growth rate
Predator
Prey
Random dispersion
R-strategist
Symbiosis
Uniform dispersion
Zero pop. growth
I can list the levels of ecological organization in order starting with the smallest & explain each
I can differentiate between habitat and niche
I can explain the different types of species interactions (symbiosis)
I can analyze graphical data in a J or S shaped curve
I can explain the reasons for the human population growth
I can explain why the predicted human population growth rate is dropping
I can interpret age structure diagrams and correlate different diagrams with different types of
countries
Ex. Rapid growth in a developing or third world country
Ex. Negative or no growth with an older developed country such as the US
