Which statement best explains why each river has its own set of characteristics? - A river supports different organisms, depending on where it flows.
- A river absorbs oxygen from the atmosphere as it flows downhill.
- Rivers interact with the ecosystems through which they pass.
- Rivers flow downhill, pulled by gravity toward the sea.

its the cell wall and the they are unique to plant

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
