The top-down model of biomanipulation involves manipulating higher trophic levels to affect lower trophic levels. Removing tertiary consumers (such as a predator) can lead to an increase in the number of secondary consumers (such as herbivores), which in turn can lead to a decrease in the number of primary producers (such as plants). This is because the removal of the predator releases the pressure on the secondary consumers, allowing their population to increase and consume more primary producers.
