The place where an organism lives and that provides the things the organism needs is called its

• habitat.

• population.

• species.

• community.

The smallest unit of ecological organization is a single

• population.

• community.

• organism.

• ecosystem.

Which of the following is an example of a population?

• the cats and dogs in your neighborhood

• the bushes and grass in a park

• the rocks in a rock collection

• the gray wolves in a forest

If you count 20 beetles in a garden measuring 5 square meters, the population density of the beetles is

• 100 beetles per square meter.

• 20 beetles per square meter.

• 5 beetles per square meter.

• 4 beetles per square meter.

Counting the number of organisms in a small area and multiplying to estimate the number in a larger area is called

• direct observation.

• mark and recapture.

• population density.

• sampling.

A group of antelope leaving the herd in search of better grassland is an example of

• birth rate.

• death rate.

An organism’s particular role in its habitat, or how it makes its living, is called its

• carrying capacity.

• ecosystem.

• competition.
