Fish production, water provisioning, and enjoyment are all supported by aquatic ecosystems (rivers, lakes, groundwater coastal waters, and seas).
In contrast to land-based terrestrial ecosystems, an aquatic ecosystem is one that exists in and around a body of water.
Aquatic ecosystems are made up of colonies of creatures that are reliant on one another and their surroundings.
Marine ecosystems and freshwater ecosystems are the two main types of aquatic ecosystems.
Freshwater ecosystems can be lentic (slow-moving water, such as pools, ponds, and lakes), lotic (faster moving water, such as streams and rivers), or wetlands (areas where the soil is saturated or inundated for at least part of the year).
