These two graphs show the amount of food consumed by a single species of organism. One graph shows food intake during one week in the summer when the organism is very active. One graph shows food intake during one week in the winter, when the organism is mostly at rest. Which graph represents each time period? Why are the two graphs different? Explain your answer, citing multiple pieces of specific evidence from the graph. Also, explain how the graph provides evidence that food is important for organisms.

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
