The scientific term for the study of interactions between organisms in an ecosystem is called ecology. This field examines the relationships between living organisms, including their interactions with each other and their environment. Ecologists study various aspects, such as population dynamics, community structure, and ecosystem functioning. They analyze how abiotic factors, like climate and soil type, influence biotic components of the ecosystem. Ecological research provides insights into biodiversity, conservation, and the effects of human activity on ecosystems, ultimately aiming to understand how to maintain ecological balance and promote sustainability.
