Understanding Population Ecology Concepts

Front

Population in population ecology

Back

A group of individuals that belong to the same species that live in the same area at the same time

Front

Which term describes the number of individuals per unit area?

Back

Population density

Front

What is a limiting factor in population ecology?

Back

A factor that restrains the growth of a population

Front

Explain how population density can affect the growth rate of a population.

Back

High density can lead to competition for resources, which may slow down the growth rate.

Front

Which model of population growth describes a situation where growth slows or stops after a period of exponential growth?

Back

Logistic growth

Front

How does carrying capacity influence the logistic growth model?

Back

It limits the population size to a sustainable level.

Front

Population with initial size of 100, growth rate 10% per year. Calculate size after one year using exponential growth.

Back

110 individuals

Front

Impact of a sudden decrease in a limiting factor on a population's growth rate.

Back

The growth rate will increase as the population can expand more freely.

Front

If a population's growth rate is slowing down, what might this indicate about the population's relationship to its environment?

Back

The population is approaching or has reached its carrying capacity.

Front

Evaluate the effects of population dispersion on resource allocation within an ecosystem.

Back

Clumped dispersion can lead to resource depletion in certain areas.
