What is the minimum amount of species required to sustain the ocean's ecosystem?
Hello there, I’m doing some research for a fantasy world I’m building.
In the story, a war between humans and fishmen ends when a genius wizard creates a set of aquatic animals and microorganisms that consume all available biomass, starving the fishmen to extinction and leaving the ocean mostly desolate.
Naturally, wiping out all life in the oceans would have devastating consequences for land ecosystems as well. But the wizard was smart enough to anticipate that, and had already prepared another set of organisms to recolonize the empty sea and take the place of what had been lost.
Ignoring the most immediate effects of all life being erased from the oceans, what might this intelligently-designed replacement ecosystem look like? More specifically, what is the simplest self-sustaining marine ecosystem that could still perform most of the functions the old one did, such as producing oxygen, supporting coastal animals as a food source, and keeping the oceans biologically active?
Let’s assume this world is roughly comparable to Earth in size and in the ratio of land to water.
