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.
Answer:
This is in order to maintain the species number of chromosomes.
Explanation:
Reduction division occurs by meiosis and it is very necessary in organisms that reproduce sexually.
Meiosis will take place in the ovary and testis to produce haploid gametes that have half the number of chromosomes compared to the parent cell .
During fertilization the two gametes will fuse to form the offspring an offspring with the same number of chromosomes as the parent. The species number of chromosome has been maintained.
Without meiosis or reduction division the off-springs would have double the chromosomes as the previous generation did.
Because it is meant to be like that for animals , us humans dont need all the stuff that animals do.
