Other seaweed may be used as fertilizer, compost for landscaping, or to combat beach erosion through burial in beach dunes. [55] Seaweed is under consideration as a potential source of bioethanol. [56] [57] Seaweed is lifted out of the top of an algae scrubber/cultivator, to be discarded or used as food, fertilizer, or skin care.
Seaweed that's attached to rocks or the sea floor is still growing, and shouldn't be removed. But anything that you find floating in the waves or strewn on the shore is fair game.
Terrestrial invertebrates such as isopods, amphipods, polychaetes, and shore flies feed on seaweed and other dead material. [3] These invertebrates provide food for shore birds and other predators on the beach. In addition, when organic debris decomposes, it delivers nutrients to the soil, promoting the growth of coastal vegetation. [1]
As in many marine ecosystems, copepods represent a major food source for a variety of neustonic and surface-associated species. [ 1 ] The sea surface microlayer (SML) at the air-sea interface is a distinct, under-studied habitat compared to the subsurface and copepods, important components of ocean food webs, have developed key adaptations to ...
Most people have experienced seaweed during a visit to the beach or as part of a meal of sushi. Seaweed is also an ingredient in many other everyday items people normally wouldn't consider -- like ...
Seaweed might be the greatest untapped resource we have on this planet, writes Vincent Doumeizel. Opinion: Seaweed is nutritious, not slimy. Eating it could save the world.
The fungus-like protist saprobes are specialized to absorb nutrients from nonliving organic matter, such as dead organisms or their wastes. For instance, many types of oomycetes grow on dead animals or algae. Marine saprobic protists have the essential function of returning inorganic nutrients to the water.
Seaweed were generally considered homologues of terrestrial plants, [11] but are only very distantly related to plants, and have evolved plant-like structures through convergent evolution. [12] Where plants have leaves, stems, and reproductive organs, kelp have independently evolved blades, stipes, and sporangia .
