The vertical divisions of marine ecosystems are determined by the distance from land and the depth of the ocean floor. Collection of living matter enclosed by a barrier that separates the cell from its surroundings; basic unit of all forms of life.

Most freshwater species of bryozoans belong to the Phylactolaemata class, while several species that tolerate brackish water belong to the Gymnolaemata class. You can see most of the water we use came from surface-water sources, such as rivers and lakes.About 26 percent of water used came from groundwater. The two horizontal divisions of marine ecosystems are the and . Ponds and lakes may have limited species diversity since they are often isolated from one another and from other water sources like rivers and oceans. Plankton, marine and freshwater organisms that, because they are nonmotile or too small or weak to swim against the current, exist in a drifting state. This paper reviews the types, extent, biodiversity and ecology of freshwater wetlands in the region, and documents the main threats to wetland ecosystems. So we could say fresh, freshwater, non-salty water. Trophic level, step in a nutritive series, or food chain, of an ecosystem.The organisms of a chain are classified into these levels on the basis of their feeding behaviour.The first and lowest level contains the producers, green plants.The plants or their products are consumed by the second-level organisms—the herbivores, or plant eaters.
