Answer 1

Answer:

So when wood come in contact with water for a long time it rot.

Explanation:

When the moisture level is sufficient, the wood rot fungi start digesting the proteins and sugars contained in the wood fiber. There are two kinds of wood rot: wet rot and dry rot. Both require wood, moisture, oxygen and warmth to grow. They do not grow well in water logged wood because of a lack of oxygen.
