If a toxic chemical where introduced to the hippo environment, then nothing too major would happen, because most of the organisms in this environment have a lot of biomass, so they would not be greatly affected. The only way for many organisms to die would be if there was biomagnifacation, but there must be a great amount of bioacculmulation for that to occur.
If one of these organisms were to die out, let's say hippos, again, nothing very big would happen because all the other organisms eat everything else. The only major thing that would occur is the population becoming extinct.
