Which best explains how the human body obtains energy from food a. by inhaling oxygen into the lungs. b. by exhaling carbon dioxide. c. by removing dangerous wastes. d. by breaking chemical bonds

by breaking and reforming chemical bonds

D.by breaking chemical bonds

Explanation:

The human beings are complex organisms which obtains energy by breaking the chemical bonds present in the food. The food we eat is composed of complex molecules of carbohydrates, fats and proteins which are digested by the fluids present in the stomach. The chemical bonds present between the molecules and atoms are broken during digestion process into simple substances which can be digested and absorbed by the body easily to obtain energy.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
