Asoybean farmer applies a pesticide to his crops each year. after several years, he notices that the pesticide seems to have less of an effect on the insects. the population of insects is now more resistant to the pesticide. would this be an example of artificial or natural selection? briefly explain your answer.

The given case is an illustration of natural selection. Natural selection refers to the phenomenon on the basis of which the organisms that get amended with the environment, seem to thrive and generate more offspring. The theory was first postulated by Charles Darwin and is now considered to be the prime reason, which results in evolution.  

Similarly, in the given question, the insects who could withstand the environment around them continue to reproduce, in comparison to those who could not cope up with the environment, thus, this would be regarded as an illustration of natural selection.  

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

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.
