Vedclass · Answer

(B) The age of a woody tree can be determined by counting the number of annual rings present in the secondary xylem of the trunk.In temperate regions,the cambium is active during the spring and less active during the autumn,leading to the formation of distinct light-colored spring wood and dark-colored autumn wood.Together,these two layers form one annual ring,which represents one year of growth.Therefore,counting these rings provides an accurate estimate of the tree's age,a field of study known as dendrochronology.
