Beta (β) diversity refers to diversity

Options

A. Between communities
B. Between two eco zones
C. Within a community
D. Within a population

Answer

**Step-by-Step Solution:**

1. **Understanding Beta Diversity**: Beta (β) diversity is a measure of the diversity between different communities or ecosystems. It indicates how many species are unique to each community and how they differ from one another.

2. **Identifying Options**: The question provides four options:
- A) Between communities
- B) Between two ecosystems
- C) Within a community
- D) Within a population

3. **Analyzing Each Option**:
- **Option A (Between communities)**: This option aligns with the definition of beta diversity, which focuses on the differences in species composition between distinct communities.
- **Option B (Between two ecosystems)**: While this option is somewhat related, beta diversity specifically refers to communities rather than ecosystems as a whole.
- **Option C (Within a community)**: This option describes alpha diversity, which measures diversity within a single community.
- **Option D (Within a population)**: This option refers to genetic diversity within a population, which is not related to beta diversity.

4. **Conclusion**: Based on the analysis, the correct answer is **Option A**: Beta diversity refers to diversity between communities.
