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.

Genetic variation is caused by mutations in the gametes and meiosis.
The large ears of the rabbits may help them hear when predators are coming. If they hear them coming, then they may be able to escape.
A polar bear with dark fur would be more obvious to its prey, who would more easily avoid him. The other white ones can blend in better and have a less chance of being detected by prey.
Organisms have genetic variation
The conditions change
The ones better at coping... survive
Survivors breed and pass on their variation
natural selection occurs
Some bacteria are more resistant
Antibiotic is added
Some bacteria survive
The survivors reproduce
Low levels of antibiotic remain
