The diversity of organisms sharing the same habitat or community is termed as
(a) alpha diversity
(b) beta diversity
(c) gamma diversity
(d) delta diversity

Options

A. alpha diversity
B. beta diversity
C. gamma diversity
D. delta diversity

Explanation

To solve the question regarding the type of diversity of organisms sharing the same habitat or community, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the term that describes the diversity of organisms within the same habitat or community.

2. **Identify the Types of Diversity**:
- **Alpha Diversity**: Refers to the diversity within a particular area or ecosystem, measured by the number of species present in that specific habitat.
- **Beta Diversity**: Involves comparing the diversity between two different ecosystems or habitats, focusing on the differences in species composition.
- **Gamma Diversity**: Represents the overall diversity across a larger region, combining both alpha and beta diversity.
- **Delta Diversity**: Refers to the diversity between different gamma diversities, influenced by changes in species and their abundance.

3. **Analyze Each Option**:
- **Option A (Alpha Diversity)**: This is the diversity within a single habitat or community.
- **Option B (Beta Diversity)**: This is not applicable as it compares two different habitats.
- **Option C (Gamma Diversity)**: This refers to overall diversity across larger regions, not just a single habitat.
- **Option D (Delta Diversity)**: This relates to changes between different gamma diversities, not relevant to a single habitat.

4. **Select the Correct Answer**: Since the question specifically refers to organisms sharing the same habitat or community, the correct answer is **(a) Alpha Diversity**.

### Final Answer:
The diversity of organisms sharing the same habitat or community is termed as **(a) Alpha Diversity**.
