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.
A schematic of Antarctic currents. Movement of surface water away from the continent pulls water up from depth. The Southern Ocean is the largest HNLC region in the global ocean. The surface waters of the Southern Ocean have been widely identified as being rich in macronutrients despite low phytoplankton stocks.
Plankton also make up the base of the marine food web, providing food for all the trophic levels above. Recent studies have analyzed the marine food web to see if the system runs on a top-down or bottom-up approach. Essentially, this research is focused on understanding whether changes in the food web are driven by nutrients at the bottom of ...
Microorganisms have key roles in carbon and nutrient cycling, animal (including human) and plant health, agriculture and the global food web. Microorganisms live in all environments on Earth that are occupied by macroscopic organisms, and they are the sole life forms in other environments, such as the deep subsurface and ‘extreme’ environments.
Meanwhile, the majority live in squalor, haul water from communal spigots, and eat highly processed food wafers made by the Soylent Corporation — a large food processing firm. Their mainstay products, Soylent Red and Soylent Yellow, are a staple food, and the latest product, a new, more nutritious, and flavorful wafer derived from plankton ...
Since phytoplankton need the sun’s rays to produce energy, they are usually found close to the surface of the water. Now, zooplankton are animals. They feed on nutrients in the water ...
Recent studies of marine microzooplankton found 30–45% of the ciliate abundance was mixotrophic, and up to 65% of the amoeboid, foram and radiolarian biomass was mixotrophic. [5] Phaeocystis is an important algal genus found as part of the marine phytoplankton around the world.
