constant death rate of the lifespan of an organism high death rate early in life birth, death, immigration, emmigration occurs when there are abundant resources occurs when a population begins to run out of resources measure of the maximum number of organisms the habitat can support affect carrying capacity such as predators, food sources, parasites affect carrying capacity such as the amount of water, light, oxygen increase as the population size grows unrelated to population density

1. type II curve

constant death rate of the lifespan of an organism

2. type III curve

high death rate early in life

3. factors that can affect population size and growth

birth, death, immigration, emmigration

4. exponential growth

occurs when there are abundant resources

5. logistic curve

occurs when a population begins to run out of resources

6. carrying capacity

measure of the maximum number of organisms the habitat can support

7. biotic limiting factors

affect carrying capacity such as predators, food sources, parasites

8. abiotic limiting factors

affect carrying capacity such as the amount of water, light, oxygen

9. density dependent factors

increase as the population size grows

10. density independent factors

unrelated to population density
