Some members of this group, specifically some , are well known for their ability to cause diseases like anthrax, tetanus, and gonorrhea.

Bacteria.

Explanation:

Anthrax is caused by rod-shaped, gram-positive bacteria which is known as Bacillus anthracis. It is found in the soil (naturally) and affects domestic and wild animals.

Tetanus is caused by the bacterium known as Clostridium tetani. It is commonly present in the soil, dust, saliva, and manure.

Gonorrhea is called an STD (sexually transmitted disease). It’s caused by infection with the bacterium known as Neisseria gonorrhoeae.

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
