#Removal of Phytoplankton#

^w^ Phytoplankton produce carbohydrates and oxygen through the process of photosynthesis and provide the vast meadowland on which thousands of species of animals graze.  

^w^ If this vital food source did not exist, zooplankton would die out, causing the starvation of small fish and eventually leading to the depletion of large fish and the apex predators.
