Due to Natural Selection, it is likely that the allelic frequency would change to favor iguanas with webbed feet. Those animals with webbed feet would have an easier time navigating their environment, which gives them an advantage over those that do not. Hope this helped!
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.
