Answer:
If there is low genetic diversity, she needs to introduce something into the system to increase the variation. I would suggest breeding the orange trees with other new orange trees to change the allele frequencies, which is called gene flow.
Likely the fungi are attacking them somewhere that they have decreased resistance, and if more alleles were introduced, there would probably be evolution towards a genotype that promotes defense against these fungi.
Answer:
The answer will be pyramid of biomass.
Explanation:
As it goes up the pyramid, the number decreases.
In the large rainfall is some water remains in the top of the soil the rest of this water is seeped into the ground.
<u>Explanation:</u>
- Mainly the absorption of water by the ground depends upon the nature and the fertility of the soil.
- When the ground receives the water it mainly accounts for the absorption and then there will be a runoff. The absorption helps to raise the level of groundwater for future usage.
- The amount of water that can get into the soil mainly depends upon the permeability of the soil surface. The water which can't infiltrate in the soil runs off into the water bodies.
- The water is an essential requirement for survival and the existence of biological organisms.
