Population Dynamics Review

Anything that limits the growth of a population like food, water, habitat, and number of mates in that environment.

• Limiting Factors

• Carrying capacity

• Logistic Growth

• Exponential Growth

• Survival

This type of pattern of growth occurs when the birth rate in a specific time period is continuous causing quick population increase and when resources are unlimited resulting in a J-shaped curve

• Decreasing growth

• Equilibrium Growth

• Logistic Growth

• Exponential Growth

• Stable growth

This pattern of growth occurs when the population rapidly increases in size until it reaches a certain point, called the carrying capacity. At this time, the resources are not enough to support the population. This results in an S-shaped curve.

• decreasing growth

• Equilibrium Growth

• Logistic Growth

• Exponential Growth

• Stable Growth

Human population growth appears to not have a carry capacity even though scientist have estimated the natural carry capacity of humans on Earth to be about 1 billion. How can this be explained?

• Humans have found new ways to reduce the effects of limiting factors.

• Humans now consume less resources than they did in the past

• Humans have used more of Earth so more people can fit.

• The earth has continued to grow at the same rate as the human population.

• Do to increased Biodiversity, plants and animals are thriving today providing more natural resources
