Which statement describes the steps for chemical cycling in an old-growth forest? a) trees create soil erosion, decay occurs, and trees take up soil nutrients. b) trees shade the ground, decay is slow, and trees take up soil nutrients. c) trees lose leaves, nutrients run off the soil, and soil erodes. d) trees create soil erosion, nutrients evaporate, and trees give off oxygen. e) trees take up soil nutrients, decay is slow, and trees give off oxygen.

B) Trees shade the ground, decay is slow, and trees take up soil nutrients.

Explanation:

If you have ever been through a forest or a forest, you may have noticed that the soil in these environments is covered with organic matter. Leaves, branches, trees and even animals that end their natural life cycle end up disposing there, becoming great sources of nutrients after decomposition. Remember that in nature nothing is lost!

This process is known as “nutrient cycling,” which in other words means a continuous exchange of life-essential substances that takes place from soil to plants, and vice versa. In a dynamic interdependence, trees and plants return to the soil what has been "consumed" for their development, through the fall of leaves, fruits, and other things that will decompose, and thereafter, through the flow of energy, end up. getting back that extra little help.

This process occurs in the following steps: Trees shade the ground with falling leaves and fruits, decay is slow, and trees absorb soil nutrients from the decay.

a "theory" a suggestion that is not 100 % accurate, or a figure. some people say its a theory because they of all the passed theory's about one subject. it depends sometimes theory might be accurate and sometimes they are.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
