The correct answer is: B. Ecology
Ecology is the scientific study of the interactions between organisms and their environment. It is a broad field that encompasses the study of the physical environment, the biotic environment, and the interactions between the two.
Ecology is important because it helps us understand how organisms are affected by their environment and how they can affect their environment in turn. This understanding can be used to manage natural resources, protect endangered species, and develop sustainable practices.
Ecology is a relatively new field of study, having emerged in the late 19th century. However, it has quickly become one of the most important fields of science, as it is essential for understanding the world around us.
The other options are incorrect because:
- Etiology is the study of the causes of disease.
- Botany is the study of plants.
- Biology is the scientific study of life.
