Autecology is defined as the of interrelationship of

Explanation

Autecology is a branch of biology which studies the relationship between a single species and its environment. The interrelationship between the same species of organisms and their environment is what is studied in autecology. This includes factors such as the abiotic (non-living) and biotic (living) components of the environment, as well as how the organism interacts with these components. Option A is incorrect because it refers to the study of many species of organisms and their environment, which is actually the definition of synecology. Option C is also incorrect because organisms in the atmosphere are studied in a branch of ecology known as aerobiology. Option D is incorrect because organisms under the earth's surface are studied in a branch of ecology known as subterranean ecology. Therefore, the correct answer is option B, which is the study of the interrelationship between the same species of organisms and their environment.
