Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of a Tree Trunk:**
- A tree trunk consists of various layers, including the cambium, inner bark, outer bark, sapwood, and heartwood.

2. **Identifying the Layers:**
- The outer bark is the protective layer of the tree, followed by the inner bark, which contains phloem tissues for nutrient transport. Beneath the inner bark is the cambium, which is responsible for the growth of the tree.

3. **Defining Sapwood and Heartwood:**
- Sapwood is the layer of wood that is actively involved in the transport of water and minerals. Heartwood, on the other hand, is the innermost part of the tree that is no longer involved in transport and is typically harder and denser.

4. **Identifying Alburnum:**
- Alburnum is described as the decently formed wood found between the bark and the hardened heartwood. It is characterized by its pale yellow or white color.

5. **Conclusion:**
- Alburnum is also known as sapwood, as it is responsible for the transport of water and minerals to various parts of the tree.

**Final Answer:**
Alburnum is also called sapwood.
