Ms. Rivera is demonstrating an experiment that includes the use of a compass. A compass has a small magnet that rotates to align with Earth's magnetic field. This small magnet of the compass is called a needle. The model below shows the experiment that Ms. Rivera is demonstrating. What will most likely happen to the compass needle when the switch is closed and the circuit parts are connected to the battery?

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.
