What does the diversity of birds and animals signify in aquatic ecosystems?

The presence of a diverse range of birds and animals in aquatic ecosystems is widely recognized as an indicator of stable ecosystem health. Biodiversity contributes to the resilience of these ecosystems, allowing them to better withstand environmental changes and stressors. A variety of species often signifies that the ecosystem has balanced food webs, adequate habitats, and a variety of biological interactions, which are essential for the sustainability of the ecosystem.

Conversely, high pollution levels typically compromise biodiversity, leading to declining populations and species loss, while the presence of invasive species often disrupts native populations and reduces overall diversity. Overpopulation of fish can lead to imbalances in the ecosystem, as it may result in overgrazing of aquatic plants and depletion of resources, further harming the health and diversity of the ecosystem. Thus, a robust and diverse community of birds and animals highlights a healthy, stable aquatic environment.
