Population Dynamics Review

Front

What happens to the population when the death rate is higher than the birth rate?

Back

The population decreases.

Front

What are Density Independent Limiting Factors?

Back

Factors that affect population size regardless of the population's density, such as natural disasters and climate.

Front

What is the equation for a stable population?

Back

BR + I = DR + E (Birth Rate + Immigration = Death Rate + Emigration)

Front

What is Logistic Growth?

Back

A pattern of growth where the population increases rapidly until it reaches carrying capacity, resulting in an S-shaped curve.

Front

What does the equation BR + I > DR + E indicate?

Back

It indicates an increasing population.

Front

What are Density Dependent Limiting Factors?

Back

Factors that affect population size based on the population's density, such as competition and predation.

Front

What is Exponential Growth?

Back

A pattern of growth where the population increases rapidly without any limiting factors, resulting in a J-shaped curve.

Front

What is carrying capacity?

Back

The maximum population size that an environment can sustain indefinitely.

Front

What is the difference between immigration and emigration?

Back

Immigration is the arrival of individuals into a population, while emigration is the departure of individuals from a population.

Front

What is the significance of the S-shaped curve in population dynamics?

Back

It represents logistic growth, where the population grows rapidly and then stabilizes at carrying capacity.
