Which of the following animals will provide the best soil aeration? 1.wolf
2.earthworm
3.fox
4.grasshopper

The correct answer is - option 2. earthworm.

Explanation:

Soil aeration is one of the major factors that help in the productivity of the soil, it is the phenomenon that exchanges the gases between the atmosphere and soil. Microbes and plants leads to change in the oxygen and carbon dioxide in the soil. Volume of the macropores, oxygen, CO2, redox potential helps in the determining the soil aeration.

Earthworms are the natural way of the help in the status of the soil aeration as they help in the increasing the volume of the macropores in the soil asnd help. They help in increasing soil porosity which increases the air and gases in the soil.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
