    The largest and most complex marine algae are called seaweeds. In contrast, the most complex freshwater forms are the Charophyta, a division of green algae which includes, for example, Spirogyra and stoneworts. Algae that are carried passively by water are plankton, specifically phytoplankton.

    en.wikipedia.org/wiki/Marine_food_web

    At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton. The second trophic level (primary consumers) is occupied by zooplankton which feed off the phytoplankton. Higher order consumers complete the web. There has been increasing recognition in recent years that marine microorganisms.

    Bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, [63] and the deep portions of Earth's crust. Bacteria also live in symbiotic and parasitic relationships with plants and animals.

    The spores of freshwater algae are dispersed mainly by running water and wind, as well as by living carriers. [83] However, not all bodies of water can carry all species of algae, as the chemical composition of certain water bodies limits the algae that can survive within them. [83] Marine spores are often spread by ocean currents.

    en.wikipedia.org/wiki/Marine_protists

    Marine protists are defined by their habitat as protists that live in marine environments, that is, in the saltwater of seas or oceans or the brackish water of coastal estuaries. Life originated as marine single-celled prokaryotes (bacteria and archaea) and later evolved into more complex eukaryotes. Eukaryotes are the more developed life forms ...

    Chlamydomonas (/ ˌ k l æ m ɪ ˈ d ɒ m ə n ə s,-d ə ˈ m oʊ-/ KLAM-ih-DOM-ə-nəs, -⁠də-MOH-) is a genus of green algae consisting of about 150 species [2] of unicellular flagellates, found in stagnant water and on damp soil, in freshwater, seawater, and even in snow as "snow algae". [3]

    Cloudy water can be a warning that there are more germs in the water than normal. Discolored or smelly water could mean there is a harmful algal bloom in the water.

    en.wikipedia.org/wiki/Marine_prokaryotes

    "The findings break from the traditional interpretation of marine ecology found in textbooks, which states that nearly all sunlight in the ocean is captured by chlorophyll in algae. Instead, rhodopsin-equipped bacteria function like hybrid cars, powered by organic matter when available—as most bacteria are—and by sunlight when nutrients are ...
