Solution : The correct option is 1866 .
The German biologist Ernst Haeckel was the first to characterise ecology as a distinct branch of study in 1866. Greek terms "oikos", which means "house" or "environment", and "logos", which means "study" or "science", were combined by Haeckel to create the word "ecology". With an emphasis on the connectivity of living things and their surroundings, he defined ecology as the study of the interactions between organisms and their environment.
