How do tigers affect prey populations in their ecosystems?

As an apex predator, the tiger plays a critical role in maintaining the health and balance of its ecosystem by controlling the populations of its prey. By hunting animals such as deer and wild pigs, tigers prevent these species from overpopulating and dominating their biological communities, which helps preserve local biodiversity.123

In addition to directly regulating prey numbers, the presence of a top predator can influence the behavior of other animals within the ecosystem. Tigers also exert influence over other predators, such as leopards and dholes, further shaping the structure of the food chain. Because tigers require large territories to support their needs, their survival is intrinsically linked to the availability and density of their prey; when prey populations decline, tigers may face increased pressure, sometimes leading them to rely on domestic livestock, which can result in conflict with human populations.3145
