These organisms are the once that produce the energy, and the organisms in the trophic levels above them use their energy to survive. If the autotrophs are removed from and ecosystem, the ecosystem will collapse, as there will be no source of energy for the organisms in the trophic levels above, thus all of them will die out quickly.
