Population Dynamics

Front

What is population dynamics?

Back

Population dynamics is the study of how populations change over time and space, including factors such as birth rates, death rates, immigration, and emigration.

Front

What are the three types of population dispersion?

Back

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

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support.

Front

What happens to a prey population when a new predator is introduced?

Back

The death rate of the prey population typically increases due to predation.

Front

What is the effect of a declining predator population on prey species?

Back

If predator populations decline, prey populations may increase due to reduced predation pressure.

Front

Define 'clumped dispersion' in population dynamics.

Back

Clumped dispersion is when individuals in a population are grouped together in patches, often due to resource availability.

Front

What is the significance of the 'death rate' in population dynamics?

Back

The death rate is crucial for understanding population growth and decline, as it directly affects the overall population size.

Front

How does immigration affect population size?

Back

Immigration increases population size by adding new individuals from other areas.

Front

What is the relationship between predators and prey in an ecosystem?

Back

Predators help control prey populations, which can prevent overgrazing and maintain ecosystem balance.

Front

What is the role of competition in population dynamics?

Back

Competition for resources can limit population growth and lead to changes in population size and structure.
