Pop. Dynamics

Front

What is a density independent limiting factor?

Back

A factor that affects population size regardless of the population's density, such as natural disasters.

Front

What is a density dependent limiting factor?

Back

A factor that affects population size based on the population's density, such as food availability.

Front

Define abiotic factors in an ecosystem.

Back

Nonliving components that affect the environment, such as temperature, sunlight, and soil type.

Front

What is carrying capacity?

Back

The maximum number of individuals of a species that an environment can sustainably support.

Front

List three abiotic factors that affect an environment.

Back

Temperature, wind, and soil type.

Front

What is the difference between abiotic and biotic factors?

Back

Abiotic factors are nonliving (e.g., water, sunlight), while biotic factors are living organisms (e.g., plants, animals).

Front

Give an example of a density independent factor.

Back

Natural disasters like hurricanes or wildfires.

Front

Give an example of a density dependent factor.

Back

Competition for food among individuals in a population.

Front

What role do abiotic factors play in an ecosystem?

Back

They influence the living conditions and resources available for organisms.

Front

How do natural disasters impact population dynamics?

Back

They can drastically reduce population sizes regardless of density.
