Which exposed wood will decay faster?

1. Sapwood
2. Softwood
3. Wood with lot of fibres
4. Heartwood

Correct answer: Sapwood

Solution

Sapwood is the younger, outer wood that still contains more moisture, nutrients, and active cells, making it more vulnerable to fungal attack and decay. Heartwood is older and usually more resistant because it has fewer nutrients and more natural protective substances.
