What is the primary role of carnivores in aquatic ecosystems?

Carnivores play a critical role in aquatic ecosystems by helping to control populations of herbivores. By predating on herbivores, they help maintain a balance within the food web, ensuring that no single species becomes too dominant, which could lead to overgrazing of plant species and subsequent habitat degradation. This predation not only regulates herbivore populations but also facilitates the growth and health of aquatic vegetation, which in turn supports a diverse range of other species.

Maintaining this balance is essential for the overall health of the ecosystem, as it ensures that energy flows appropriately through the food web, supporting various trophic levels. Through their interactions, carnivores contribute to nutrient cycling, habitat structure, and biodiversity, ultimately promoting a resilient aquatic environment.
