The study of the relationships between organisms and their environments is called ecology. This field examines how living organisms interact with each other and with the abiotic components of their environment, such as climate, soil, and water. Ecologists investigate various levels of organization, from individual organisms to ecosystems and the entire biosphere. They study topics like food webs, population dynamics, and the impact of human activities on natural habitats. Understanding these relationships is vital for addressing environmental issues and promoting sustainable practices to protect ecosystems and biodiversity.
