How do tiger sharks help stop overgrazing of seagrass beds?

Tiger sharks play a crucial role in maintaining the health of seagrass beds by regulating the populations of herbivorous species, such as turtles and certain fish, that graze on seagrass. By preying on these herbivores, tiger sharks help prevent overgrazing, allowing seagrass ecosystems to thrive. This balance supports biodiversity and the overall health of marine habitats, as seagrass beds provide essential services like carbon sequestration and nursery grounds for various marine species.
