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.
Nitrogen is found in all living cells. Without nitrates, a plant cannot grow and produce flowers and seeds. This is primarily because nitrogen is an essential component of plant proteins and chlorophyll, which is necessary for the process of photosynthesis. Photosynthesis is how a plant makes food. Without nitrates, photosynthesis cannot occur, and the plant will die from a lack of food.
(Image: NASA-MODIS/Aqua). 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.he Changing Nitrogen Cycle. Look up into the sky and you look through millions of air molecules, eighty percent of which are nitrogen molecules-two atoms of nitrogen bonded together. Nitrogen is found all over the planet, not just in the sky. It is in living things, air, water, even animal waste.
