People also ask, what would happen if plankton went extinct?
If the phytoplankton are disappearing, Richardson says, "the ocean as a carbon sink is declining, and what that means is ultimately more CO2 will stay in the atmosphere instead of being dissolved in the ocean." That will translate into a warmer world, which will wipe out even more phytoplankton.
Likewise, what would happen if all ocean life died? The collapse of ocean bio-diversity and the catastrophic collapse of phytoplankton and zooplankton populations in the sea will cause the collapse of civilization, and most likely the extinction of the human species. And that is why when the ocean dies, we all die!
Considering this, what happens when phytoplankton die?
In the aftermath of a massive bloom, dead phytoplankton sink to the ocean or lake floor. The bacteria that decompose the phytoplankton deplete the oxygen in the water, suffocating animal life; the result is a dead zone.
Why is phytoplankton important to life on Earth?
Photosynthesis by the phytoplankton accounts for up to half of global primary production. They also provide the primary food source for the zooplankton, and together form the base of the oceanic food chain. Larger and larger zooplankton, fish, and mammals depend on these plankton for their survival.
