1. Logistic Growth

early on populations will exhibit very rapid growth but as they near the carrying capacity they will level off, producing an S shaped curve

2. Density Dependent

the growth is affected by the density of the individuals

3. Density Independent Factors

adverse weather, floods, droughts, cold temperatures, etc

4. Cohort

a group of individuals born at the same time, e.g. baby boomers

5. Life Table

(also known as Survivorship Schedule)
age specific death schedule, for each age interval there is a predicted life expectancy

6. R-Selected Organisms

put most of their energy into rapid growth and reproduction
e.g. weeds, rabbits, fish

7. K-Selected Organisms

put most of their energy into growth
e.g. trees, humans

8. Community Ecology

the study of how different species interact within communities

9. Habitat

the physical place where an organism lives, e.g. a pine forest or freshwater lake

10. Niche

the functional role of an organism in a community, its job or position
