The primary influence of seasonal changes on biodiversity is the availability of resources such as light, water, and nutrients, which can affect species' abundance and distribution. For instance, in temperate zones, seasonal changes significantly influence the timing of reproduction, migration, and growth patterns among different species. As seasons shift, organisms adapt their life cycles to synchronize with changes in environmental conditions, showcasing the dynamic interplay between climate and biodiversity. This adaptability is essential for maintaining healthy ecosystems.
