Coconut is a large and heavy fruit. How is it adapted for dispersal by water?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Coconut's Structure**: The coconut is a large and heavy fruit, but it has specific adaptations that allow it to disperse effectively by water.

2. **Fibrous Outer Layer**: The outer covering of the coconut is made of a fibrous layer. This fibrous layer is crucial because it contributes to the overall lightness of the coconut despite its size.

3. **Buoyancy**: The fibrous layer allows the coconut to float on water. This buoyancy is essential for water dispersal, as it enables the coconut to be carried away by water currents.
