Population Dynamics

Front

What is population density and how is it calculated?

Back

Population density is the number of individuals living in a defined space divided by the area of that space.

Front

What is carrying capacity in the context of population dynamics?

Back

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

Front

What does the logistic growth model describe?

Back

The logistic growth model describes how a population grows rapidly at first, then slows as it approaches the carrying capacity of its environment.

Front

What factors can lead to an increase in population size?

Back

An increase in population size can occur when the birth rate is greater than the death rate.

Front

What is competition in an ecological context?

Back

Competition occurs when organisms struggle for limited resources in their environment.

Front

What are the two main types of population growth models?

Back

The two main types of population growth models are exponential growth and logistic growth.

Front

What is the difference between biotic and abiotic factors in an ecosystem?

Back

Biotic factors are living components of an ecosystem, while abiotic factors are non-living components, such as climate and soil.

Front

How do limiting factors affect population growth?

Back

Limiting factors, such as food availability, predation, and disease, can restrict population growth and keep it below the carrying capacity.

Front

What role does immigration play in population dynamics?

Back

Immigration can increase the size of a population by adding new individuals from other areas.

Front

What is the significance of the birth rate in population studies?

Back

The birth rate is significant as it directly influences the growth rate of a population.
