Transcript

What the lesson says

What is a population, and what is a community?

Here is a pond, a home for many living things.

Fish of one kind live in the water.

All the fish of this kind in the pond make a population.

A population is all of one kind of living thing in one place.

The frogs are all one kind too, so they make another population.

The ducks are one kind as well, so they are a population too.

Plants count too, so these cattails of one kind make a population.

What do we call all these populations together?

All the populations in the pond together make a community.

A community is all the populations that live in one place.

A population is all of one kind, and a community is all the kinds living together.
