  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

    A top-down cascade is a trophic cascade where the top consumer/predator controls the primary consumer population. In turn, the primary producer population thrives. The removal of the top predator can alter the food web dynamics. In this case, the primary consumers would overpopulate and exploit the primary producers. Eventually there would not ...

    Secondary consumers are small/medium-sized carnivores that prey on herbivorous animals. Omnivores, which feed on both plants and animals, can be considered as being both primary and secondary consumers. Tertiary consumers, which are sometimes also known as apex predators, are hypercarnivorous or omnivorous animals usually at the top of food ...

    The terrestrial forest (summer) and the English Channel ecosystems exhibit inverted pyramids.Note: trophic levels are not drawn to scale and the pyramid of numbers excludes microorganisms and soil animals. Abbreviations: P=Producers, C1=Primary consumers, C2=Secondary consumers, C3=Tertiary consumers, S=Saprotrophs. [6]

    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

  9. Macrocystis - Wikipedia

    en.wikipedia.org/wiki/Macrocystis

    Giant kelp grows in dense stands known as kelp forests, which are home to many marine animals that depend on the algae for food or shelter. The primary commercial product obtained from giant kelp is alginate, but humans also harvest this species on a limited basis for
