    The green scum shown in this image is the algae bloom in Lake Erie. Within aquatic ecosystems, algae assumes a pivotal role by utilizing photosynthesis to transform water and carbon dioxide into sugar, concurrently releasing oxygen as a by-product. However, inadequate management can create significant environmental consequences.

  3. Ocean fertilization - Wikipedia

    en.wikipedia.org/wiki/Ocean_fertilization

    In waters with sufficient iron micro nutrients, but a deficit of nitrogen, urea fertilization is the better choice for algae growth. [31] Urea is the most used fertilizer in the world, due to its high content of nitrogen, low cost and high reactivity towards water. [32]

  4. Algaculture - Wikipedia

    en.wikipedia.org/wiki/Algaculture

    Dulse is one of many edible algae. Algaculture may become an important part of a healthy and sustainable food system [11]. Several species of algae are raised for food. While algae have qualities of a sustainable food source, "producing highly digestible proteins, lipids, and carbohydrates, and are rich in essential fatty acids, vitamins, and minerals" and e.g. having a high protein ...

    Algae grown in floating farms could be harvested and used for food or fuel. All biological life is made up of lipids, carbohydrates, amino acids, and nucleic acids. Whole algae could be turned into animal feed, fertilizer, or bio-char. Separating the lipids from the algae could also create bio-diesel from the lipid content and bio-char from the ...

  7. Reactive oxygen species production in marine microalgae

    en.wikipedia.org/wiki/Reactive_oxygen_species...

    Since iron is necessary for phytoplankton growth, the auto-reduction of reactive oxygen species may be a way for algae to get usable iron from free or organically bound ferric iron. [73] For instance, Cakman et al. [ 74 ] showed that ROS may increase the amount of iron available through extracellular ferric reduction.

  8. Algal bloom - Wikipedia

    en.wikipedia.org/wiki/Algal_bloom

    A very large algae bloom in Lake Erie, North America, which can be seen from space. An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in fresh water or marine water systems. It is often recognized by the discoloration in the water from the algae's pigments. [1]

  9. Marine food web - Wikipedia

    en.wikipedia.org/wiki/Marine_food_web

    But most of the primary production by algae is performed by the phytoplankton. Thus, in ocean environments, the first bottom trophic level is occupied principally by phytoplankton, microscopic drifting organisms, mostly one-celled algae, that float in the sea. Most phytoplankton are too small to be seen individually with the unaided eye. They ...
