Human Population Growth

Front

What is the definition of carrying capacity?

Back

The largest population size of a species that can be supported by the environment.

Front

What happens to a population when it reaches its carrying capacity?

Back

Birth and immigration rates are equal to death and emigration rates.

Front

What is the impact of human technology on carrying capacity?

Back

Human technology has been responsible for periodically increasing the carrying capacity.

Front

What is the formula to calculate the new population size?

Back

New Population = Initial Population + Births + Immigrants - Deaths - Emigrants.

Front

If a population starts with 100 people, 10 immigrate, 20 emigrate, 15 are born, and 5 die, what is the new population?

Back

100 + 15 + 10 - 5 - 20 = 100; No change.

Front

What is the relationship between birth rate and death rate at carrying capacity?

Back

At carrying capacity, the birth rate equals the death rate.

Front

What is the significance of a low death rate in Stage 4 of population growth?

Back

A low death rate indicates a stable population with high life expectancy.

Front

What are limiting factors in population growth?

Back

Environmental conditions that restrict the growth of a population, such as food, water, and space.

Front

What is exponential growth in population dynamics?

Back

A growth pattern where the population size increases rapidly due to abundant resources.

Front

What is emigration?

Back

The act of leaving one's resident country to live elsewhere.
