Fish and other aquatic life depend on oxygen gas dissolved in the water. which event is most likely to harm aquatic life by reducing the oxygen concentration of the water? a change in weather that reduces the temperature of the lake by 5°c an influx of warm water that raises the temperature of the lake by 5°c a sunny day that lowers the water level of the lake by 50 centimeters a rainstorm that raises the water level of the lake by 50 centimeters

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 a good question! i'll do some research and come back when i have the answer!

d. planting trees

the trees take in carbon to make oxygen.

links? do you have a link? i don't see anything?
