Educational worksheet on aquatic ecosystems with images and descriptions of different water environments.

Let’s match each term on the left with its correct description or example on the right.

We’ll go one by one:

1. Wetlands → These are areas where water covers the soil most of the year.
✔ Match: *fresh water covers the soil most of the year.*

2. Standing water → This refers to water that doesn’t flow — like ponds and lakes.
✔ Match: *ponds and lakes*

3. Open sea → The open ocean is the largest ecosystem on Earth.
✔ Match: *largest ecosystem*

4. Shoreline → This is where the sea meets the land.
✔ Match: *the sea and the land meet.*

5. Flowing water → Rivers and streams have moving (flowing) water.
✔ Match: *rivers and streams*

6. Coral reefs → These grow in warm tropical waters.
✔ Match: *warm tropical waters*

Now let’s write the final matched pairs clearly.
