How does competition in ecosystems affect organisms?

Competition in ecosystems affects organisms by influencing their survival, growth, and reproductive success. When multiple species or individuals vie for the same resources, such as food, water, or habitat, it can lead to resource scarcity, driving some organisms to adapt, migrate, or face decline. This competition can shape community dynamics, leading to evolutionary changes over time and affecting biodiversity. Ultimately, it plays a crucial role in determining the structure and function of ecosystems.
