If they went extinct the whole food chain would be out of balance.
If the number of phytoplankton decrease the food chain would decrease in the ocean.
If phytoplankton became extinct, a wide range of marine organisms would face starvation, particularly those that rely directly on phytoplankton as their primary food source, such as zooplankton. This, in turn, would impact larger marine animals, including small fish, which depend on zooplankton, and ultimately larger predators like whales, seals, and seabirds. The loss of phytoplankton would disrupt the entire marine food web, leading to significant declines in biodiversity and ecosystem health.
It would be extinct. As in no longer in existence. It would not be here anymore.
other animals that relied on it would die and come extinct
we would all be in caves or extinct
They become extinct.
they will be extinct
It would effect the food chain and other marine life would become extinct
bullfighters would be out of a job
then you would not even be here
Then there would be no human nature.
You mom will disappear
