The dominant species of mangroves is

Options

A. Rhizophora
B. Avicennia
C. Both Rhizophora and Avicennia
D. Ceriops.

Answer

**Step-by-Step Solution:**

1. **Understanding Mangroves**: Begin by noting that mangroves are specialized shrubs or small trees that thrive in coastal saline environments. They are adapted to survive in areas where freshwater meets saltwater.

2. **Identifying Dominant Species**: The question asks for the dominant species of mangroves. Dominant species are those that are most prevalent and play a significant role in the ecosystem.

3. **Key Species of Mangroves**: The two primary species of mangroves that are often considered dominant are:
- **Rhizophora** (commonly known as red mangrove): This species typically colonizes the seaward side of mangrove forests and is known for its ability to withstand tidal flooding.
- **Avicennia** (commonly known as black mangrove): This species is usually found further inland at higher elevations compared to Rhizophora.

4. **Analyzing Options**:
- The options provided include:
- Rhizophora
- Avicennia
- Both Rhizophora and Avicennia
- Cereops (which is a genus, not a species)
- Since both Rhizophora and Avicennia are dominant species of mangroves, the correct answer would be "both Rhizophora and Avicennia."

5. **Conclusion**: Therefore, the dominant species of mangroves is both Rhizophora and Avicennia.
