Biodiversity plays a crucial role in maintaining the stability of ecosystems by ensuring that each part of the system can adapt to changes and continue functioning smoothly. Different species fulfill specific roles, contributing to processes like nutrient cycling, disease regulation, and climate control. A wide variety of organisms allows ecosystems to recover more quickly from disturbances, such as natural disasters or human impacts, and prevents any one species from becoming too dominant, which could disrupt the balance. Essentially, biodiversity is like a safety net, with each species providing a backup that helps the entire system remain resilient in the face of challenges.
