The correct answer is: D. Ecology
Ecology is the scientific study of the interactions between organisms and their environment. It is a relatively new field of science, having only emerged as a distinct discipline in the early 20th century. However, it has quickly become one of the most important and interdisciplinary fields of science, as it is essential to understanding the complex web of interactions that sustain life on Earth.
Ecology is concerned with the study of ecosystems, which are communities of organisms that interact with each other and with their environment. Ecosystems can be very small, such as a pond or a forest, or they can be very large, such as the entire planet.
Ecologist study the relationships between organisms and their environment in order to understand how ecosystems function. They also study how ecosystems are affected by human activities, such as pollution and climate change.
Ecology is a vital field of science, as it provides us with the knowledge we need to protect our planet and its resources. By understanding how ecosystems work, we can make informed decisions about how to manage our environment in a sustainable way.
The other options are incorrect because they are not concerned with the study of the environment.
- Geography is the study of the Earth’s surface and its features.
- Ethnology is the study of human cultures.
- Geology is the study of the Earth’s physical structure and history.
