Phytoplankton Food Chain In The Ocean

Phytoplankton has declined 40 in 60 years as figures reveal Earth has been getting hotter since the Eighties.

Phytoplankton food chain in the ocean. The Word Phytoplankton is derived from the Greek words Phyto plant and plankton made to wander or drift. Are the producers of the ocean food chain. Food chainsor food websof lakes and other freshwaters also depend on phytoplankton for their food.

But environmental changes and human activities may be threatening plankton - and therefore all. The food chain is organized into trophic levels and the base trophic level or bottom rung of this system contains organisms that make their own food. Countless billions of one-celled organisms called phytoplankton saturate sunlit upper-ocean waters worldwide.

The more phytoplankton present in the ocean water the greater the concentration of plant pigments. The foundation of the seas food chain is largely invisible. On the oceans surface waters microscopic.

Small fish and invertebrates also graze on the plant-like organisms and then those smaller animals are eaten by bigger ones. Phytoplankton are on the bottom of the aquatic food chain so their nourishment and population growth are essential to other creatures from the small fish that eat them to larger fish and eventually humans. An increase in the proportion of primary production by nano- and picophytoplankton has qualitative as well as quantitative consequences for future food production from the oceans since this is where the biosynthesis of important components.

Also some types of algae seaweed unicellular plants bacteria etc. Phytoplankton consist mostly of algae and bacteria and are the foundation of the marine food chain. Larger and larger zooplankton fish and mammals depend on these plankton.

In a balanced ecosystem they provide food for a wide range of sea creatures. In a balanced ecosystem they provide food for a wide range of sea creatures. These small plants are very important to the ocean and to the whole planet.
