A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Lentic ecosystems can be compared with lotic ecosystems, which involve flowing terrestrial waters such as rivers and streams. Together, these two ecosystems are examples of freshwater ecosystems. Lentic systems are diverse, ranging from a small, temporary rainwater pool a few inches deep to Lake Baikal, which has a maximum depth of 1642 m. [10]
This is a list of freshwater ecoregions as compiled by the World Wildlife Fund (WWF). The freshwater ecoregion system is similar to that for terrestrial ecoregions.The Earth's land surface is divided into eight terrestrial biogeographic realms or ecozones, which contain hundreds of smaller ecoregions.
Oxsjön, a lake in Sweden. Freshwater biology focuses on environments like lakes. A pond in the Oconee River Floodplain in Georgia, whose surface is covered in duckweed but still contains fish. Freshwater biology is the scientific biological study of freshwater ecosystems and is a branch of limnology. This field seeks to understand the ...

Freshwater ecosystem. Freshwater ecosystems are a subset of Earth's aquatic ecosystems. They include lakes, ponds, rivers, streams, springs, bogs, and wetlands. [15] They can be contrasted with marine ecosystems, which have a larger salt content. Freshwater habitats can be classified by different factors, including temperature, light ...
3 Food web structure. 4 Species ... Intertidal ecology is the study of intertidal ecosystems, ... Low salinities can be caused by rainwater or river inputs of freshwater.
In a way, mycoplankton contributions to aquatic food webs are the biogeochemical services that they perform. The grazer food chain and the microbial food chain are inherently intertwined, as the dissolved organic carbon at the base of the microbial food chain originally comes from material excreted by grazers from the grazer food chain.
