Community ecology deals with

Options

A. The study of changes in population size
B. The study of changes in population size
C. The interrelationships between the organisms of different species
D. Ecological Niche

Answer

**Step-by-Step Solution:**

1. **Understanding Community Ecology**: Community ecology is a branch of ecology that focuses on the interactions between different species within a community. It examines how these interactions influence the structure and dynamics of the community.

2. **Analyzing the Options**: The question provides several options regarding what community ecology deals with:
- Option 1: The study of change in population size.
- Option 2: The study of change in population size (repeated).
- Option 3: The inter-relationship between organisms of different species.
- Option 4: Ecological niches.

3. **Evaluating Each Option**:
- **Option 1**: While population size is important, community ecology specifically focuses on interactions among different species rather than just changes in population size.
- **Option 2**: This is a repeat of Option 1 and does not provide any new information.
- **Option 3**: This option correctly identifies that community ecology deals with the inter-relationships between organisms of different species, which is a fundamental aspect of this field.
- **Option 4**: Ecological niches refer to the role of a species within its ecosystem, which is related but not the primary focus of community ecology.

4. **Conclusion**: Based on the analysis, the correct answer is Option 3, as it accurately describes the focus of community ecology on the inter-relationships between organisms of different species.

**Final Answer**: Community ecology deals with the inter-relationship between organisms of different species.
