Question

Shown below is a cross-section of two different trees of same species and age but found in different locations. Based on the image, which of the statement(s) is/are TRUE.

• A. Growth of the tree X is more consistent than tree Y
• B. Growth of the tree X is healthier than tree Y
• C. Climatic conditions could be the reason for the uneven ring structures in tree Y
• D. Growth of the tree Y is healthier than tree X

Answer 1

The Correct Option is A, B, C

The provided image shows the cross-section of two trees, which can be analyzed by examining the growth rings. The cross-section of a tree reveals its growth pattern over the years. Here are the conclusions based on the given options: 

• Growth of the tree X is more consistent than tree Y: Consistent growth in a tree is indicated by uniformly spaced rings. Tree X shows such uniformity, suggesting steady growth across the years.
• Growth of the tree X is healthier than tree Y: Uniform and well-defined growth rings in Tree X suggest it experienced favorable growing conditions consistently, which typically implies healthier growth compared to irregular rings found in Tree Y.
• Climatic conditions could be the reason for the uneven ring structures in tree Y: Uneven growth rings occur due to variations in climate, such as droughts or excess rainfall, affecting the growth rate each year. Tree Y's irregular rings suggest potential climatic impacts.

Summary: The statements about Tree X having more consistent and healthier growth than Tree Y, as well as climatic conditions affecting Tree Y's growth, are true based on the visual evidence in the cross-section images.
