There would be a disbalance in the entire ecosystem as there would be a sudden surge in the prey population which would result in decreasing of food availability of herbivores, thereby causing the decline in the population of the species that are present in the lower trophic levels. The wetlands thrum with the secret messages of a thousand wild sounds. By preventing overpopulation by a species, the jaguar helps to keep the food chain balanced for a healthy environment. Elephants are the cornerstone in a healthy savanna. Without the jaguar, herbivorous prey animals would decimate the plants of their ecosystem.
