  2. Kelp forest - Wikipedia

    en.wikipedia.org/wiki/Kelp_forest

    Frequently considered an ecosystem engineer, kelp provides a physical substrate and habitat for kelp forest communities. [16] In algae (kingdom Protista ), the body of an individual organism is known as a thallus rather than as a plant (kingdom Plantae ).

  3. Marine food web - Wikipedia

    en.wikipedia.org/wiki/Marine_food_web

    This happens because the ocean's primary producers are tiny phytoplankton which grow and reproduce rapidly, so a small mass can have a fast rate of primary production. In contrast, many significant terrestrial primary producers, such as mature forests , grow and reproduce slowly, so a much larger mass is needed to achieve the same rate of ...

  4. Kelp - Wikipedia

    en.wikipedia.org/wiki/Kelp

    More than 100,000 mobile invertebrates per square meter are found on kelp stipes and holdfasts in well-developed kelp forests. [30] While larger invertebrates and in particular sea urchins ( Strongylocentrotus droebachiensis ) are important secondary consumers controlling large barren ground areas on the Norwegian coast, they are scarce inside ...

  5. Marine ecosystem - Wikipedia

    en.wikipedia.org/wiki/Marine_ecosystem

    Kelp forests occur worldwide throughout temperate and polar coastal oceans. [10] In 2007, kelp forests were also discovered in tropical waters near Ecuador. [11] Physically formed by brown macroalgae, kelp forests provide a unique habitat for marine organisms [12] and are a source for

  6. Foundation species - Wikipedia

    en.wikipedia.org/wiki/Foundation_species

    Californian forest of giant kelp, a foundation species [1]. In ecology, the foundation species are species that have a strong role in structuring a community.A foundation species can occupy any trophic level in a food web (i.e., they can be primary producers, herbivores or predators).

  7. Consumer (food chain) - Wikipedia

    en.wikipedia.org/wiki/Consumer_(food_chain)

    A consumer in a food chain is a living creature that eats organisms from a different population. A consumer is a heterotroph and a producer is an autotroph . Like sea angels, they take in organic moles by consuming other organisms, so they are commonly called consumers.

  8. Food web - Wikipedia

    en.wikipedia.org/wiki/Food_web

    Position in the food web, or trophic level, is used in ecology to broadly classify organisms as autotrophs or heterotrophs. This is a non-binary classification; some organisms (such as carnivorous plants) occupy the role of mixotrophs, or autotrophs that additionally obtain organic matter from non-atmospheric sources.

    Kelp forests occur worldwide throughout temperate and polar coastal oceans. [55] In 2007, kelp forests were also discovered in tropical waters near Ecuador. [56] Physically formed by brown macroalgae, kelp forests provide a unique habitat for marine organisms [57] and are a source for
