Front

What is immigration in population dynamics?

Back

Immigration refers to the movement of individuals into a population from other areas.

Front

What is emigration in population dynamics?

Back

Emigration is the movement of individuals out of a population to other areas.

Define a community in ecology.

Back

A community is made up of different types of organisms living in the same area.

Front

What is a population in ecology?

Back

A population is a group of the same type of organisms that live together in a specific area.

Front

What does logistic growth look like on a graph?

Back

Logistic growth is represented by an 'S' curve.

Front

What is exponential growth in population dynamics?

Back

Exponential growth occurs when a population increases rapidly without any limiting factors, often depicted as a 'J' curve.

Front

What are density-dependent limiting factors?

Back

Density-dependent limiting factors are factors that affect population size in relation to the population's density, such as competition and disease.

Front

What are density-independent limiting factors?

Back

Density-independent limiting factors are factors that affect population size regardless of the population's density, such as natural disasters and unusual weather.

Front

Give an example of a density-dependent limiting factor.

Back

Competition among individuals for resources is a density-dependent limiting factor.

Front

Give an example of a density-independent limiting factor.

Back

Natural disasters, like hurricanes or wildfires, are density-independent limiting factors.
