Population Ecology

Front

What is logistic growth in population ecology?

Back

Logistic growth is a model of population growth that describes how a population grows rapidly initially, then slows as it approaches the carrying capacity of its environment.

Front

What are the three phases of logistic growth?

Back

Phase 1: Rapid growth, Phase 2: Slower growth, Phase 3: Growth stops.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum population size that an environment can sustain indefinitely without being degraded.

Front

What is emigration in population ecology?

Back

Emigration is the process by which individuals leave a population, leading to a decrease in population size.

Front

What is immigration in population ecology?

Back

Immigration is the process by which individuals move into a population, leading to an increase in population size.

Front

What are the different types of population dispersion?

Back

The three main types of population dispersion are clumped, uniform, and random.

Front

What does clumped dispersion mean?

Back

Clumped dispersion occurs when individuals are grouped together in patches, often due to resource availability or social behavior.

Front

What is exponential growth in population ecology?

Back

Exponential growth is a model of population growth where the population size increases at a constant rate, resulting in a J-shaped curve when graphed.

Front

What factors can limit population growth?

Back

Factors that can limit population growth include resource availability, predation, disease, and environmental conditions.

Front

How does carrying capacity affect population growth?

Back

As a population approaches its carrying capacity, the growth rate slows down and may eventually stop due to limited resources.
