There are three basic types of freshwater ecosystems: Lentic (slow moving water, including pools, ponds, and lakes), lotic (faster moving water, for example streams and rivers) and wetlands (areas where the soil is saturated or inundated for at least part of the time).

Fish cages containing salmon in Loch Ailort, Scotland, an inshore water. Inshore mariculture is farming marine species such as algae, fish, and shellfish in waters affected by the tide, which include both littoral waters and their estuarine environments, such as bays, brackish rivers, and naturally fed and flushing saltwater ponds.
The ocean surface is a crucial interface for oceanic and atmospheric processes. Allowing interchange of particles, enriching the air and water, as well as grounds by some particles becoming sediments. This interchange has fertilized life in the ocean, on land and air. All these processes and components together make up ocean surface ecosystems.
A humpback whale (Megaptera novaeangliae) A leopard seal (Hydrurga leptonyx). Marine mammals are mammals that rely on marine (saltwater) ecosystems for their existence. They include animals such as cetaceans (whales, dolphins and porpoises), pinnipeds (seals, sea lions and walruses), sirenians (manatees and dugongs), sea otters and polar bears.
An ecosystem (or ecological system) is a system formed by organisms in interaction with their environment. [2]: 458 The biotic and abiotic components are linked together through nutrient cycles and energy flows.
A stream of airborne microorganisms circles the planet above weather systems but below commercial air lanes. [92] Some peripatetic microorganisms are swept up from terrestrial dust storms, but most originate from marine microorganisms in sea spray. In 2018, scientists reported that hundreds of millions of viruses and tens of millions of ...
The profundal zone is the deep zone of a lake, located below the range of effective light penetration.This is typically below the thermocline, the vertical zone in the water through which temperature drops rapidly.
