  2. Lake ecosystem - Wikipedia

    en.wikipedia.org/wiki/Lake_ecosystem

    Lake ecosystems are a prime example of lentic ecosystems (lentic refers to stationary or relatively still freshwater, from the Latin lentus, which means "sluggish"), which include ponds, lakes and wetlands, and much of this article applies to lentic ecosystems in general.

  3. Pond - Wikipedia

    en.wikipedia.org/wiki/Pond

    The technical distinction between a pond and a lake has not been universally standardized. Limnologists and freshwater biologists have proposed formal definitions for pond, in part to include 'bodies of water where light penetrates to the bottom of the waterbody', 'bodies of water shallow enough for rooted water plants to grow throughout', and 'bodies of water which lack wave action on the ...

  4. Freshwater ecosystem - Wikipedia

    en.wikipedia.org/wiki/Freshwater_ecosystem

    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 ...

  5. Freshwater biology - Wikipedia

    en.wikipedia.org/wiki/Freshwater_biology

    Freshwater biology is the scientific biological study of freshwater ecosystems and is a branch of limnology. This field seeks to understand the relationships between living organisms in their physical environment. These physical environments may include rivers, lakes, streams, ponds, reservoirs, or wetlands. [1]

  6. Pond life - Wikipedia

    en.wikipedia.org/wiki/Pond_Life

    Frogs in a pond. Pond life is an umbrella term for all life forms found in ponds.Although there is considerable overlap with the species lists for small lakes and even slow-flowing rivers, pond life includes some species not found elsewhere, and as a biome it represents a unique assemblage of species.

  7. Aquatic ecosystem - Wikipedia

    en.wikipedia.org/wiki/Aquatic_ecosystem

    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]

  8. Limnology - Wikipedia

    en.wikipedia.org/wiki/Limnology

    Phosphorus has a different role in aquatic ecosystems as it is a limiting factor in the growth of phytoplankton because of generally low concentrations in the water. [13] Dissolved phosphorus is also crucial to all living things, is often very limiting to primary productivity in freshwater, and has its own distinctive ecosystem cycling. [17]

  9. Lake - Wikipedia

    en.wikipedia.org/wiki/Lake

    For example, one widely cited study estimated that Earth has 304 million lakes and ponds, and that 91% of these are 1 hectare (2.5 acres) or less in area. [17] Despite the overwhelming abundance of ponds, almost all of Earth's lake water is found in fewer than 100 large lakes; this is because lake volume scales superlinearly with lake area. [21]
