An increase in herbivore populations in an ecosystem will soon lead to?

An increase in herbivore populations in an ecosystem will soon lead to overgrazing, which can deplete plant resources and disrupt the balance of the ecosystem. This can result in reduced plant diversity and health, affecting other organisms that rely on those plants for food and habitat. Additionally, as vegetation diminishes, soil erosion may increase, further degrading the environment. Ultimately, this imbalance can lead to population declines in herbivores due to food scarcity and increased competition.
