Gypsy moths found in the forests of england come in gray and black variations. before the industrial revolution, the gray moths outnumbered black moths in the population. as a result of the industrial revolution, soot from factories blackened trees used as habitat for the moths. the frequency of black moths began to dominate the population as they were now better camouflage from predators. the term that best describes this adaptation is stabilizing selection directional selection disruptive selection coevolution macroevolution

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.

what exactly is the question lol
