Autecology is defined as the study of Interrelationship of

Step 1: Analyze the question The question asks for the definition of autecology. Break the word into parts:

• Aut(o) = self, single
• Ecology = study of organisms and their environment

Step 2: Explain the concept Ecology has two main branches:

• Autecology: the study of a single species (an individual organism or one population of the same species) and its relationship with its environment. For example, studying how tilapia fish live, feed and reproduce in a particular pond.
• Synecology: the study of communities or groups of different species and their interrelationships with the environment. For example, studying all the plants and animals in a forest.

Step 3: Evaluate the options

• A. Many species and their environment: this is synecology, not autecology.
• B. Same species and their environment: this matches autecology.
• C, D and E: these describe particular habitats (air, soil, water), not the definition of autecology.

Step 4: Answer The correct answer is B.

Tip: Remember "Aut = Alone": autecology deals with one species alone. "Syn = Several": synecology deals with several species together.
