Population Growth Models

Front

What is carrying capacity?

Back

The largest number of individuals in a species that an environment can support long term.

Front

What happens to a population when the number of births equals the number of deaths?

Back

The population will stay the same.

Front

What type of growth is characterized by a rapid increase in population size?

Back

Exponential growth.

Front

What factors have contributed to rapid population growth in recent history?

Back

Medical care, clean water, and better access to nutritious food.

Front

What occurs when a population exceeds its carrying capacity?

Back

The population starts to die off to return to carrying capacity.

Front

Define exponential growth in the context of population dynamics.

Back

A growth pattern where the population size increases rapidly over time, typically when resources are abundant.

Front

What is logistic growth?

Back

A growth pattern that starts exponentially but slows as the population approaches the carrying capacity.

Front

What is the difference between immigration and emigration?

Back

Immigration is the arrival of individuals into a population, while emigration is the departure of individuals from a population.

Front

How does population density affect resource availability?

Back

Higher population density can lead to increased competition for limited resources.

Front

What is a boom-bust cycle in population dynamics?

Back

A pattern where a population rapidly increases and then sharply decreases due to resource depletion.
