aquatic ecosystem

An aquatic ecosystem refers to a community of living organisms—such as fish, plants, and invertebrates—and their physical environment within bodies of water like lakes, rivers, oceans, and wetlands. These ecosystems function through complex interactions where organisms depend on water quality, temperature, and nutrients for survival. They support biodiversity, regulate climate, and provide resources like food and recreation for humans. Healthy aquatic ecosystems are vital for maintaining environmental balance and ensuring the sustainability of water resources for both wildlife and human communities.
