All theories are hypotheses, but not all hypotheses are theories. francis wants to know if a specific hypothesis he is researching is a theory. which describes how francis would know the hypothesis is a theory? he could restate the hypothesis as a fact and no longer an explanation. he could determine whether the hypothesis is based on repeated experiments. he could perform the experiment and adjust data to match the desired results. he could design and perform a new controlled experiment to test the hypothesis.

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.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
