Which of the following is a primary product of forest trees?

One primary product of forest trees is timber, which is also known as wood or lumber. Timber is the wood that is harvested from trees and used for construction, furniture, and many other purposes. After the trees are harvested, they are cut into different sizes and shapes, depending on their intended use. For example, larger trees can be used for building homes and furniture, while smaller trees can be used for paper and other products. While paper, particle board, cardboard, and pulp can all be made from wood, they are not considered primary products of forest trees because they require additional processing and manufacturing steps to turn the wood into these products. In contrast, timber is the raw product that comes directly from the trees and can be used for many different purposes.
