Extinction.
There is probably a more complicated answer, but if animals can't reproduce, they go extinct.
This term is extinction.
An extinction event.
Extinct (Extinction)
The extinction rates of terrestrial and freshwater organisms varies per location. This is largely dependent on other growing and declining populations.
They could not hibernate or go very long without resources.
The process in which groups of organisms die out is called extinction. Extinction occurs when a particular species cannot adapt to changing environmental conditions or faces competition from other species, leading to their eventual disappearance.
Extinction
Extinction is part of the Theory of Evolution. This goes along with natural selection and survival of the fittest. Organisms that go extinct do so because they are no longer able to survive in the habitat.
The extinction of so many organisms left a large ecological niche to expand into, which mammals did.
The disappearance of all organisms of a specific species would be called extinction. This event can have significant ecological impacts on the ecosystem that the species once inhabited.
