Ecology describes

Options

A. Interactions between living organism only
B. Interactions between members of a single species only
C. Interactions of organisms among thermselves as well as with their surrounding abiotic components
D. Intraspecific competitions only

Answer

### Step-by-Step Solution:

1. **Understanding Ecology**: Begin by defining what ecology is. Ecology is the branch of biology that studies the interactions between organisms and their environment.

2. **Components of Ecology**: Recognize that ecology involves two main components:
- **Biological Community**: This includes all the living organisms in a particular area.
- **Physical Environment**: This includes the non-living components such as soil, water, and climate.

3. **Interaction and Exchange**: Understand that ecology focuses on how these two components interact with each other. This interaction includes the exchange of materials (like nutrients) and energy (like sunlight).

4. **Examples of Ecosystems**: Identify examples of ecosystems to illustrate the concept:
- **Natural Ecosystem**: Such as forests or ponds, where organisms interact naturally.
- **Artificial Ecosystem**: Such as crop fields, which are created and maintained by humans.

5. **Conclusion**: Based on the understanding of ecology, conclude that it describes the relationships and interactions between living organisms and their physical environment.

6. **Select the Correct Answer**: If the question provides multiple-choice options, select the option that encapsulates the definition and components of ecology, which would typically be the one that includes both biological communities and their physical environments.
