Which statement best describes how the two techniques differ in reducing fungal infestations of crop plants? a) fungicides kill plants infected with fungi, while genetic engineering modifies fungal dna. b) fungicides kill the source of food for fungi, while genetic engineering to make fungi-infected plants edible. c) fungicides interfere with fungal growth and reproduction, while genetic engineering produces plants resistant to fungi. d) fungicides change fungal dna, while genetic engineering the crops and the fungi to form a symbiotic relationship.

thermophiles, notice the prefix thermo.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
