Based on its dry weight, a freshly felled tree may contain water A. 25% B. 50% C. 75% D. 100%

25%
50%
75%
100%

The correct answer is: B. 50%

A freshly felled tree may contain up to 50% water by weight. This water is stored in the cells of the tree and helps to keep the tree alive. As the tree dries out, the water content will decrease.

Option A is incorrect because a freshly felled tree does not contain 25% water by weight. The water content of a freshly felled tree is much higher than 25%.

Option C is incorrect because a freshly felled tree does not contain 75% water by weight. The water content of a freshly felled tree is much lower than 75%.

Option D is incorrect because a freshly felled tree does not contain 100% water by weight. The water content of a freshly felled tree is much lower than 100%.
