Pollution tolerant: These organisms will be found in polluted, as well as clean aquatic ecosystems (Leeches, Blood worms) Some index worksheets combine groups 2 and 3 together, giving only 3 groups. Each group has a number assigned to it and is multiplied by the number of organisms found in that group.
An aquatic ecosystem is an ecosystem found in and around a body of water, in contrast to land-based terrestrial ecosystems. Aquatic ecosystems contain communities of organisms—aquatic life—that are dependent on each other and on their environment. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. [1]
Freshwater ecosystem. Freshwater ecosystems are a subset of Earth's aquatic ecosystems that include the biological communities inhabiting freshwater waterbodies such as lakes, ponds, rivers, streams, springs, bogs, and wetlands. [1] They can be contrasted with marine ecosystems, which have a much higher salinity. Freshwater habitats can be ...
Marine ecosystems can be divided into many zones depending upon water depth and shoreline features. The oceanic zone is the vast open part of the ocean where animals such as whales, sharks, and tuna live.
Photosymbiosis is important in the development, maintenance, and evolution of terrestrial and aquatic ecosystems, for example in biological soil crusts, soil formation, supporting highly diverse microbial populations in soil and water, and coral reef growth and maintenance. [5] [6]
In deep water, marine snow is a continuous shower of mostly organic detritus falling from the upper layers of the water column. Its origin lies in activities within the productive photic zone . Marine snow includes dead or dying plankton , protists ( diatoms ), fecal matter, sand, soot and other inorganic dust.
Water is the medium of the oceans, the medium which carries all the substances and elements involved in the marine biogeochemical cycles. Water as found in nature almost always includes dissolved substances, so water has been described as the "universal solvent" for its ability to dissolve so many substances.
