Food webs help in maintaining ecosystem stability because they:
provide alternative food sources
In a food web each organism has several food sources.
If one food source declines, consumers can switch to another, so the loss of one population does not collapse the ecosystem.
These alternative food sources keep the ecosystem stable.
Hence, the answer is that they provide alternative food sources.
