Step 1 of 3
- Count one kind: the 6 fish.
- Add the frogs, the lotus and the ducks.
- All the kinds together are the community.
The rule
A population is one kind in one place. A community is all the populations there.
The 6 fish are a population. So are the 4 frogs. The fish, frogs, lotus and ducks are the community of the pond.
Add the water and soil to the community. Then you have the whole ecosystem.
