Population and Population Limits

Factor that limits a population and is dependent on the number of organisms in the population.

• Density-dependent

• Density-independent

• Abiotic factors

• Biotic factors

Factor that limits a population and is NOT dependent on the number of organisms in the population.

• Density-dependent

• Density-independent

• Abiotic factors

• Biotic factors

All of the following are density-dependent factors that limit populations EXCEPT

• disease

• competition

• fire

• parasites

All of the following are density-independent factors that limit populations EXCEPT

• hurricane

• competition

Explains how fast a given population grows.

• Population Growth Rate

• Density Dependent Growth

• Density In-Dependent Growth

• Population Ranges

Related to birth rates and death rates.

• Population Growth Rate

• Density Dependent Growth

• Density In-Dependent Growth

• Population Ranges

Population will have this kind of growth unless some limiting factors (like food, water, space or predation) slows the population growth.

• Logistical growth

• Exponential growth

• Carrying capacity

• predator-prey

Population's growth slows or stops following exponential growth, at a population's carrying capacity.

• Logistical growth

• Exponential growth

• Carrying capacity

• predator-prey
