If a disease is continually present in a population in small amounts, it is considered an endemic disease.
a. true
b. false

TRUE

Explanation:

Endemic diseases are the diseases or infections that are persistently present in the population of a particular geographical area.

An endemic infection or disease does not increase at an exponential rate and also does not get eliminated entirely. Therefore, such an infection is constantly maintained without any external outputs and thus reaches the endemic steady state.

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
