Let’s go through each picture one by one and decide if it shows a freshwater ecosystem or not.
Remember: Freshwater means water that is NOT salty — like rivers, lakes, ponds, swamps, and streams. Saltwater ecosystems are oceans, seas, coral reefs, and beaches near the ocean.

Picture 1 (top left):
This shows a sandy beach with clear blue water and green land on one side. The water looks like the ocean — very blue and wide open. This is likely a saltwater ecosystem (ocean/coastal).
→ Not freshwater → It’s
Saltwater / Marine
---
Picture 2 (top right):
Colorful fish swimming around coral. Coral reefs only grow in warm, salty ocean water.
→ Not freshwater → It’s
Saltwater / Marine (Coral Reef)
---
Picture 3 (middle left):
Close-up of sea anemones and maybe a clownfish? These live in the ocean, usually near coral reefs.
→ Not freshwater → It’s
Saltwater / Marine

Picture 4 (middle right):
A fast-flowing river surrounded by trees and rocks. Rivers are classic examples of freshwater ecosystems.
→ Yes! →
FRESHWATER
---
Picture 5 (bottom left):
Trees growing out of calm, still water — looks like a swamp or bayou. Swamps can be freshwater (like in Louisiana or Florida). The water doesn’t look salty, and there are cypress trees which grow in freshwater swamps.
→ Yes! →
FRESHWATER

Picture 6 (bottom right):
Sunset over a wide beach with waves and birds flying. This is clearly an ocean shoreline.
→ Not freshwater → It’s
Saltwater / Marine (Beach/Ocean)

Final Answer:
Top Left: Saltwater
Top Right: Saltwater
Middle Left: Saltwater
Middle Right: FRESHWATER
Bottom Left: FRESHWATER
Bottom Right: Saltwater
Parent Tip: Review the logic above to help your child master the concept of freshwater ecosystem worksheet.
