phytoplankton diversity

in each article, they each talk about  how phytoplankton play a major role in the food chain. due to the water becoming warmer the phytoplankton are decreasing by 40%. the  phytoplankton are decreasing and there is nothing to stop it. "The work addresses how phytoplankton species are affected by a changing environment, and the really difficult question of weather adaptation to these changes us possible.

MARINE FOOD WEB

                              the marine food web is made up of all organisms living under the ocean.

     



   In this food web I was an anchovy. a lot of other organisms ate me. if I went extinct I many things would starve and die off but other had other food supplies. almost everything I ate was bacteria. animals usually eat more than one food source but sharks ate almost everything and only some whales would eat sharks.

PHYTOPLANKTON

Is made up of thousands of different species the most important are the algae known as diatoms which are 60% of planktonic life. diatoms depend on sunlight. for energy to preform photosynthesis and nutrients such as nitrogen and phosphorus to support their life process.  seasonal variations in the distribution and abundance of phytoplankton and why many marine organisms migrate to follow this food source.
