marine ecosystem

A marine ecosystem encompasses the diverse communities of living organisms and their physical environment in ocean and coastal areas. It includes saltwater habitats like oceans, coral reefs, and estuaries, where various species such as fish, mammals, plants, and microorganisms interact. These ecosystems are vital for global biodiversity, climate regulation, and human livelihoods, providing food, recreation, and tourism opportunities. Threats like pollution, overfishing, and climate change disrupt these systems, highlighting the need for conservation efforts to maintain their health and resilience. Understanding marine ecosystems is crucial for sustaining the planet's ecological balance.
