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.
Plants need nitrogen to grow. Plants are not able to use the nitrogen that is in the atmosphere for this, even though there is tons of it available. Itâs just not in a form that plants can use. So they get the nitrogen they need from the soil where bacteria have converted it into a usable form.
