Food webs are limited representations of real ecosystems as they necessarily aggregate many species into trophic species, which are functional groups of species that have the same predators and prey in a food web.
They fill a space (niche) in a food web.
food web
A food web can more readily react to changes in the environment that impact one or more species. Also a food web is sometimes strengthened by the loss of one or more species if that species is overly aggressive, whereas a food chain is only as strong as it's weakest link and is always diminished or destroyed by the loss of any member. In short, a food web is more adaptive than a food chain and usually more diverse with more opportunity for cooperative advantage, improving chances of survival over a chain for the included species, especially species higher in the web (further from photosynthesis).

Keystone species of the Chesapeake Bay food web.
It needs to eat food, and if their food is vanished then they too can die. I something in their food web goes extinct, it will also effect them.

Invasive species have caused a significant amount of damage to the Great Lakes Food Web in recent years. The alien species of fish, of 25 at least know, are in constant competition with the native fish for food and a habitat. The invasive species are also the cause of the degrading of coastal wetlands.
