D). Uterus

Explanation: Fertilization occurs in the fallopian tube. Fertilization is the fusion of a sperm and an egg to form a zygote. The zygote moves down the fallopian tube to the uterus where it gets embedded into the wall of the uterus. Its attachment to the uterine wall enables the embryo to develop. If the embryo fails to attach itself to the wall of the uterus, the pregnancy will be aborted.

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.
