The term for the study of the relationship between living organisms and their environment is ecology. This branch of biology focuses on understanding how organisms interact with each other and their surroundings, including both biotic (living) and abiotic (non-living) factors. Ecologists study various ecosystems, biodiversity, and the impact of human activities on natural environments. By examining these relationships, ecology plays a crucial role in conservation efforts, habitat restoration, and understanding the dynamics of ecosystems. The knowledge gained from ecological studies is vital for addressing environmental challenges and promoting sustainability.
