An aquatic ecosystem is a community of organisms and the physical environment in which they interact in a watery environment. There are two main types of aquatic ecosystems: freshwater and marine.

Freshwater Ecosystems

Freshwater ecosystems include lakes, rivers, streams, and ponds. These ecosystems are home to a variety of plants and animals, including fish, amphibians, and insects. They are also important sources of drinking water and support a wide range of recreational activities.

Marine Ecosystems

Marine ecosystems encompass oceans, coral reefs, and estuaries. These ecosystems are incredibly diverse and are home to a vast array of life, including fish, marine mammals, and invertebrates. Marine ecosystems play a crucial role in regulating the Earth's climate and are a vital source of food and resources for humans.
