A branch of ecology which is concerned with the study of individual species at all stages of its life cycle in relation to environment is called

Options

A. ecological niche
B. synecology
C. reproductive ecology
D. autecology

Answer

To solve the question, we need to identify the specific branch of ecology that focuses on the study of individual species throughout their life cycle in relation to their environment. Here’s the step-by-step solution:

### Step 1: Understand the Key Terms
- **Ecology**: The study of interactions between organisms and their environment.
- **Individual Species**: Refers to a single type of organism, which can be studied at various stages of its life cycle.
- **Life Cycle**: The series of stages that an organism goes through from birth to reproduction to death.

### Step 2: Identify Relevant Branches of Ecology
- **Niche**: Refers to the role and position of a species in its environment, but it does not focus solely on individual species.
- **Synchology**: This branch studies interactions between different species in a community, which is not the focus of the question.
- **Reproductive Ecology**: This focuses on the reproductive aspects of organisms and their relationship with the environment, but it does not encompass the entire life cycle.
- **Auto Ecology**: This branch specifically studies the relationship between individual organisms (or species) and their environment throughout all stages of their life cycle.

### Step 3: Conclusion
Based on the definitions and focus of each branch, the correct answer to the question is **Auto Ecology**. This branch is concerned with the study of individual species at all stages of their life cycle in relation to their environment.

### Final Answer
The branch of ecology which is concerned with the study of individual species at all stages of its life cycle in relation to the environment is called **Auto Ecology**.
