The term for the study of living organisms and their interactions is biodiversity or biosciences. This field encompasses various disciplines, including ecology, evolutionary biology, and microbiology, examining how organisms interact with each other and their environments. Understanding these relationships is crucial for grasping ecological dynamics, evolutionary processes, and the impacts of human activities on ecosystems. Additionally, studying these interactions helps inform conservation strategies, promoting biodiversity and ecosystem sustainability, which are vital for maintaining the health of our planet.
