Ecology

Ecology is the scientific study of the interactions between organisms and their environment, exploring the factors that determine the distribution and abundance of life. As a core discipline within biology, it examines relationships at multiple levels, from individual populations and communities to entire ecosystems. By analyzing the flow of energy and the cycling of essential nutrients through these systems, ecology provides the foundational understanding required to address environmental challenges and guide effective conservation.
