apex predator hypothesis

The apex predator hypothesis suggests that certain top predators play a crucial role in maintaining the balance of ecosystems. As the highest-ranking predators, they help regulate the populations of other species below them in the food chain. By controlling herbivore numbers, for example, apex predators can impact plant diversity and health. Their presence often indicates a healthy ecosystem, while their absence can lead to overpopulation of prey species, resulting in habitat degradation. Thus, apex predators are essential for ecological stability and biodiversity, highlighting their importance in natural systems.
