Ecology is the scientific study of interactions between organisms and their environment, including both biotic (living) and abiotic (non-living) components. It helps us understand how species coexist, compete, and adapt in different habitats. Ecology is important because it provides insights into ecosystem functioning, biodiversity conservation, and the sustainable use of natural resources. By studying ecological relationships, scientists can predict the impacts of human activities, climate change, and pollution, allowing for better environmental management and protection of life-supporting ecosystems on Earth.
