An ecological phenomenon refers to a natural event or process that significantly impacts ecosystems and the organisms within them. Examples include seasonal migrations of animals, pollination by insects, and nutrient cycling in ecosystems. These phenomena can influence biodiversity, food webs, and the overall health of the environment. Many ecological phenomena are interconnected, demonstrating the complex relationships between different species and their habitats. For instance, the El Niño phenomenon affects weather patterns, which in turn can alter the distribution of marine life and impact fishing industries. Understanding these events is crucial for conservation efforts and sustainable resource management.
