Removal of all the organisms in a trophic level will cause the same type of disturbance in an ecosystem, i.e., killing of higher trophic level and explosion in population of the lower level organisms. If all producers are killed, there will be no food available for herbivores present in the ecosystem. In the absence of herbivores, various categories of carnivores will be affected. Since, all categories of organisms are linked through a food chain, removal of organisms of any trophic level will ultimately affect the ecosystem.
