Answer 1

The Food chain will slowly begin to fall apart and food sources become scarce due to lack of producers. Producers are important to every food-chain and are needed for herbivores which lead on to other consumers.

Answer 2

Well for starters, since phytoplankton is a very important producer in the food web, animals that depends on phytoplankton will slowly begin extinguish. the  animals that eat phytoplankton is also a very crucial part of the web, so if the animal that eats phytoplankton dies out, more predators of that one animals will die, eventually, the whole food chain will be destroyed.
