The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
Some foods have always been common in every continent, such as many seafood and plants. Examples of these are honey, ants, mussels, crabs and coconuts. Nikolai Vavilov initially identified the centers of origin for eight crop plants, subdividing them further into twelve groups in 1935.

In 2010, researchers found that alginate, the soluble fibre substance in sea kelp, was better at preventing fat absorption than most over-the-counter slimming treatments in laboratory trials. As a food additive, it may be used to reduce fat absorption and thus obesity. [53] Kelp in its natural form has not yet been demonstrated to have such ...
If seaweeds are compared to terrestrial plants, they have a higher proportion of essential fatty acids as eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids. [16] Seaweed contains high levels of iodine, tyrosine relative to other foods. [17] It is also rich in calcium and magnesium. [18] Seaweed is a possible vegan source of Vitamin ...
A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
