Answer 1

Each ring represents one year if growth. D

Answer 2

The correct answer is option D, that is, one year of growth.

Step-by-step explanation:

Every year, the tree produces new cells, aligned in concentric circles known as annual growth rings or annual rings. These annual rings demonstrate the concentration of wood generated at the time of one growing season. The season of growth starts in the spring. Initially, the cambium generates many big cells with thin walls, which produces the springwood that appears as a light ring.

Then at the termination of the summer, growth slows down. The cells produced at the time of this year are small and comprises thick walls, the formation of summerwood takes place, which appears as a darker ring. Therefore, one year of growth is signified by a ring comprising of dark and light part.
