aquatic ecosystems
Underwater living communities
Aquatic ecosystems are biological communities found in water environments, including oceans, lakes, rivers, wetlands, and estuaries.
These systems encompass all living organisms—from microscopic plankton to whales—along with the physical and chemical properties of their watery habitat.
Scientists distinguish between freshwater ecosystems (lakes, streams, ponds) and marine ecosystems (oceans, coral reefs, tidal zones).
The oil spill devastated the aquatic ecosystem for miles along the coastline.
