Aquatic ecosystems interactive worksheet - Free Printable

Let’s match each aquatic ecosystem term with its correct description.

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 land meets the sea.
✔ 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, usually near shores but not on them — they need warmth and sunlight.
✔ Match: *warm tropical waters*

Now let’s write the final matched pairs clearly.
