How do obligate aerobes and obligate anaerobes differ in their interactions with the atmosphere? a. obligate aerobes require oxygen from the atmosphere for survival, while obligate anaerobes do not. b. obligate aerobes release carbon dioxide into the atmosphere, while obligate anaerobes release oxygen. c. obligate aerobes take in atmospheric oxygen, while obligate anaerobes take in atmospheric carbon dioxide. d. obligate aerobes cannot survive in the presence of atmospheric oxygen, while obligate anaerobes can.

The correct answer is option A, that is, obligate aerobes require oxygen from the atmosphere for survival, while obligate anaerobes do not.  

The obligate aerobes refer to the species that need oxygen in order to survive. These organisms only attain energy from aerobic respiration, with the application of oxygen as the final electron acceptor for the electron transport chain.  

On the other hand, obligate anaerobes are the species that do not utilize oxygen, however, they are poisoned by the usual levels of atmospheric oxygen, and they get killed in the presence of oxygen.

The answer for plato users is a.

Explanation:

I just did the test.

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

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
