if you grew up with a family pet, then you have surely noticed that they often seem to hear things that you don’t hear. now that you’ve read this section, you probably have some insight as to why this may be. how would you explain this to a friend who never had the opportunity to take a class like this?

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.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
