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 ...

Nymphaea (/ n ɪ m ˈ f iː ə /) is a genus of hardy and tender aquatic plants in the family Nymphaeaceae. The genus has a cosmopolitan distribution. Many species are cultivated as ornamental plants, and many cultivars have been bred. Some taxa occur as introduced species where they are not native, [3] and some are weeds. [4]
In shallow, plant-rich pools there may be great fluctuations of oxygen, with extremely high concentrations occurring during the day due to photosynthesis and very low values at night when respiration is the dominant process of primary producers. Thermal stratification in larger systems can also affect the amount of oxygen present in different ...
Biome-type: grouping of convergent biomes or formations of different continents, defined by physiognomy. Formation-type: a grouping of convergent formations. Whittaker's distinction between biome and formation can be simplified: formation is used when applied to plant communities only, while biome is used when concerned with both plants and ...
White water lilies are a typical marsh plant in European areas of deeper water. Many kinds of birds nest in marshes; this one is a yellow-headed blackbird.. Marshes provide a habitat for many species of plants, animals, and insects that have adapted to living in flooded conditions or other environments. [1]
