in the carbon and nitrogen cycles. In the carbon cycle‚ decomposing bacteria release carbon from the decaying bodies or waste into the atmosphere. Without them‚ it won’t be able for any organism to access the carbon stored in dead bodies. In the nitrogen cycle‚ decomposing bacteria breaks down animal waste‚ which creates ammonia and nitrate products rich in nitrogen. Although no animals or plants cannot directly use all the nitrogen found in the atmosphere‚ such form of nitrogen created by the bacteria

produced by the vaporization of a block of dry ice that measures 12.0 in x 12.0 in x 2.0 in? The density of the dry ice is 1.56 g/cm3 5. Two flasks of equal volume are connected by a narrow tube (of negligible volume). The flasks are filled with nitrogen gas and‚ when both are immersed in boiling water‚ the gas pressure inside the system is 0.50 atm. One of the flasks is then immersed in an ice-water mixture‚ keeping the other in boiling water. Calculate the new pressure of the system. Assume ideal

planet Earth that is retained by Earth’s gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation. A. Nitrogen - 78% - Dilutes oxygen and prevents rapid burning at the earth’s surface. Living things need it to make proteins. Nitrogen cannot be used directly from the air. The Nitrogen Cycle is nature’s way of supplying the needed nitrogen for living things. B. Oxygen - 21% - Used by all living things. Essential for respiration. It is necessary for combustion or burning

Micro-organisms Micro-organisms Micro-organisms (or microbes) are literally microscopic organisms‚ which can only be seen properly with the aid of a microscope. These include bacteria‚ microscopic fungi (moulds) and protoctists. Although viruses‚ which are even smaller than bacteria‚ are generally considered to be non- living entities‚ they might also be included here as they are important disease-causing agents. Micro-organisms are the most numerous organisms in any ecosystem. There are about 159

verses. He joined the Federal Institute of Technology situated in Zurich for pursuing more knowledge on chemical engineering and made himself master of the contemporary modern chemical technologies. He innovated a new method to combine two elements nitrogen and hydrogen in order to create ammonia. Haber was awarded with various prizes for his invention of new method of producing ammonia and finally he was nominated for Nobel Prize in 1918. A significant proportion of scientists differed against granting

Chemical Fertilizers vs. Organic Fertilizers INTRODUCTION Agriculture is the most primitive occupation of the people which mainly needs land to grow different crops for food and as raw materials for different industries. Industrial use of agriculture for supplying raw materials came much later. Originally land was used for agriculture to supply food for human beings by the use of organic manures particularly animal dung. At the beginning land was used in its natural form to grow food. Land contains

BCR : the importance of nitrogen . I suspect that your instructor had some elements that he/she explained were critical to "a Well Designed Investigation." If I were you‚ I would get those out to start with so that you can make sure that you include all in your answer. 1. Probably they include negatives and‚ if possible‚ positive controls. Is your negative control a test plant that is planted in a pot with no legume planted in the pot? Do you have any other negative controls? How about positive

Experiencing many pitfalls‚ however‚ has lead to the actual product obtained to contain the expected product‚ as well as many impurities. This report examines the supposed mechanism for the electrophilic substitution
