Cutting down only mature trees allows more resources to be available for the younger growing trees and extends the life of the forest.
Explanation:
- Older an taller trees grow to a height and forms a canopy over the forest floor.
- This cuts the maximum amount of sunlight from reaching the under growths.
- Thus the shorter and younger trees lie in shade and cannot grow properly due to lack of sunlight.
- On the other hand the trees could penetrate deeper into the soil consuming up a lot of nutrient and the competition for resources becomes maximum.
- When taller and older trees are cut, the canopy is removed and sunlight couldl penetrate to the forest floor and the stress on soil is also reduced , thus allows the growth of younger trees which in turn extends the life of the forest.

The rib cage is formed by 24 ribs (12 pairs). Their function is to protect the lungs, heart, and other internal organs of the thorax. They also enable the lungs to expand, facilitating breathing by expanding the chest cavity.
From those 12 pairs, 7 pairs are "true ribs" directly attached to the sternum and the rest are called "false ribs" because some are suspended or share cartilage that connects to sternum.
