Human Population Growth and the Environment

Human Population Growth

Population

• the same species

• in the same area and thus can interbreed

• example: all of the red maple trees in a forest

• example: all of the humans in the world

Multiple Choice

Populations whose growth is not slowing down is

• logistic

• exponential

Multiple Choice

All members of the same species who live in the same general area are considered a

• ecosystem

• group

• population

Multiple Choice

Populations cannot continue to grow indefinitely because of

• excess food

• limiting factors

• habitat expansion

Multiple Choice

The maximum number of organisms that an area can support is the

• carrying capacity

• limiting factor

• demographer

Multiple Choice

Factors that keep a population from growing:

diseases

• density dependent limiting factor

• density independent limiting factor

Multiple Choice

Factors that keep a population from growing:

natural disasters like fire, hurricanes

• density dependent limiting factor

• density independent limiting factor

Multiple Choice

Factors that keep a population from growing:

competition for food

• density dependent limiting factor

• density independent limiting factor

Multiple Choice

Factors that keep a population from growing:

Food, Water

• density dependent limiting factor

• density independent limiting factor

Multiple Choice

The children are found

• at the bottom of the age structure pyramid

• at the top of the age structure pyramid

• on the left of the age structure pyramid

• on the right of the age structure pyramid

Multiple Choice

An age structure pyramid that is wide at the bottom shows a population that is growing

• exponentially

• logistically

Multiple Choice

An age structure pyramid that is wide at the bottom shows a population in a

• developing nation

• developed nation
