How would a food web be affected if a species disappeared from an ecosystem and how do you think this food web would be affected if the plants were eliminated?
The species that make up an ecosystem are connected in complex "food webs" of eater and eaten. When one species disappears, its predators can no longer eat it and its prey is no longer eaten by it. Changes in these populations affect others. Such impact 'cascades' can be unpredictable and sometimes catastrophic. The removal of the producers would cause the collapse of the entire food web. Primary consumers or herbivores, which feed on producers directly, would die off. ... Higher level consumers would suffer as organisms from lower trophic levels start to die off
