Unit 4: Limiting Factors Independent Practice

Front

What is a limiting factor in an ecosystem?

Back

A limiting factor is something in the environment that restricts the growth, abundance, or distribution of a population within an ecosystem.

Front

What happens to a population when the birth rate is greater than the death rate?

Back

The population will grow.

Front

What is population density?

Back

Population density is the number of individuals per unit area.

Front

Give an example of a limiting factor for a rabbit population in a forest ecosystem.

Back

Grass available.

Front

What effect does a disease that destroys a food source have on the population of animals that rely on that food?

Back

The population of those animals would decrease.

Front

What is carrying capacity?

Back

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

Front

How does emigration affect population size?

Back

Emigration decreases the population size.

Front

What is the relationship between birth rate and population growth?

Back

If the birth rate exceeds the death rate, the population will grow.

Front

What is the significance of sunlight in an ecosystem?

Back

Sunlight is a crucial limiting factor as it affects photosynthesis and the energy available for producers.

Front

What is the impact of high population density on resources?

Back

High population density can lead to resource depletion and increased competition.
