Determining the weight of 100 CDs depends on whether only the CDs are weighed or if the CDs have sleeves or jewel cases. A single CD by itself weighs about 0.58 ounces. Therefore, 100 CDs by themselves weigh 58 ounces.
Plants and animals need nitrogen in order to make proteins. Proteins are essential compounds for healthy growth and fully functioning organisms. However, nitrogen is often in short supply to plants in both natural and agricultural systems. If nitrogen supply limits the growth of plants then the animals which feed on the plants will also suffer.
Nitrification is important because plants can only use nitrogen in the nitrate form. However, when more ammonia is nitrified than plants can use, the unused nitrate will accumulate in the soil. Second, applying more nitrate fertilizer to the soil than a crop can use will build up high levels of nitrate.Finally, legume plants, such as alfalfa, can take nitrogen out of the air and put it into the ground through their root nodules.This process is called nitrogen fixation.itrification is important because plants can only use nitrogen in the nitrate form.
