Explanation:
Detailed explanation-1: -Age of a tree can be estimated by counting the number of annual rings in a cut stem. The two kinds of wood (spring and autumn wood) appear as alternate concentric rings of light and dark colour, respectively.
Detailed explanation-2: -EXPLANATION: The most accurate way to determine the age of a tree is to count the annual rings of wood growth. Annual rings can be counted using two different methods. One can extract an increment core from the tree using an increment borer.
