Unit 5: Population Dynamics

Front

What is emigration?

Back

Emigration is the act of leaving one's resident country with the intent to settle elsewhere.

Front

What factor most likely causes emigration?

Back

Resource scarcity is a primary factor that can lead to emigration as individuals seek better living conditions.

Front

What does the range of tolerance refer to?

Back

The range of tolerance refers to the environmental limits within which a species can survive and reproduce.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum population size of a species that an environment can sustain indefinitely without degrading the environment.

Front

What is a biotic limiting factor?

Back

Biotic limiting factors are living components of an ecosystem that affect population size, such as predation, competition, and disease.

Front

Which factor is NOT a biotic limiting factor?

Back

Soil quality is considered an abiotic factor, not a biotic limiting factor.

Front

How does a drought affect carrying capacity?

Back

During a drought, the carrying capacity of an ecosystem decreases due to reduced water availability and food resources.

Front

What is an abiotic factor?

Back

Abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems.

Front

Give an example of a biotic factor.

Back

An example of a biotic factor is the presence of predators, which can limit the population size of prey species.

Front

What is population density?

Back

Population density is the number of individuals of a species per unit area or volume.
