QUESTIONS Based on the diagram shown below, what would be the effect of treating the soil with an antibiotic that killed all bacteria? Nitrogen (N2) in atmosphere Assimilation SA by plants ints Amino acids and proteins in plants and animals Nitrogen fixation des Denitrifying bacteria Nitrates Nitrogen-fixing bacteria in root nodules of legumes (NO,-) ISK IN LIS 080) Detriti Nitrifying bacteria itivores 1 Decomposition Nitrogen-fixing Nitrogen bacteria in soil fixation Ammonium (NH) OS OK- K A Plants growing in the soil would be unable to build amino acids B. Animals feeding off of plants growing in the soil would be unable to build amino acids. Atmospheric nitrogen would be inaccessible to plants or animals. D. The nitrogen in the amino acids of dead plants and animals would be inaccessible to living plants. E. All of the above
Question 5: The correct answer is E.
All of the above.
Explanation: If we treat the soil with an
antibiotic that killed all the bacteria, then the nitrogen fixation
would not take place. Therefore, plants would not be able to use
atmospheric nitrogen. Thus plants would be unable to build amino
acids. Thus further processes such as nitrification,
denitrification would not take place.
