During the annual migration from Florida to Mexico, the Ruby-Throated Hummingbird must fly 450 miles over water without stopping. One year, a hurricane swept through the migration route and killed 90% of the hummingbirds. Although 10% of the birds survived, their genetic variation has been threatened by this occurrence. What is a probable consequence for the hummingbird population?

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

i think that it is plants
