B. individual species and its enviroment
C. between biotic and abiotic factor
D. all of the above

Answer

### Step-by-Step Solution:

1. **Understanding Synecology**: Synecology is a branch of ecology that focuses on the study of groups of organisms and their interactions with each other and their environment.

2. **Defining the Components**: In synecology, we consider various types of organisms (different species) and how they interact within a community. This includes their relationships with both biotic factors (living organisms) and abiotic factors (non-living elements like temperature, light, and soil).

3. **Distinguishing from Orthoecology**: It is important to differentiate synecology from orthoecology, which studies individual organisms and their interactions with the environment. Synecology, on the other hand, looks at the community level.

4. **Conclusion**: Therefore, synecology is the study of relationships between groups of various types of organisms along with their environment, including both biotic and abiotic factors.

### Final Answer:
Synecology is the study of the relationship between groups of various types of organisms along with their environment.
