Living thing need air to breath. Air unseen and untouchable. Air are consist of nitrogen, oxygen, carbon dioxide and other gaseous. Nitrogen is an important element for the living organisms to live and to form the complex organic molecules such as proteins and amino acids. However, most of the living organisms such as plants can only use the nitrogen which already in compound form because the pure nitrogen is inactive and the strong triple bond between its atoms are difficult to break. In order to produce nitrogen that is in compound form, it has to undergo a process known as nitrogen cycle. There are five important processes to create the nitrogen cycle which are nitrogen fixation, nitrification, assimilation, ammonification and denitrification …show more content…
Ammonification is the process that carried out by a variety of microorganisms that breaks down proteins, amino acids, and other nitrogen containing compounds in dead and waste organic matter to form ammonia. Nitrogen in biomass is returned to the ecosystem by degradation of the macromolecules gathered from proteins and nucleotides and referred to as mineralization (Ward, 2013). Ammonification usually occurs under aerobic conditions with the liberation of ammonia or ammonium ions which are either released to the atmosphere or utilized by plants such as corn, paddy,weeds and other plants and microorganisms or still under favorable soil conditions oxidized to form nitrites and then to nitrates. The bacteria that complete the ammonification process are Bacillus, Clostridium, Proteus, Pseudomonas, and Streptomyces and known as ammonifying bacteria. The important step in ammonification is deamination which means removal of the amino group from proteins and amino acids and results in the discharge of ammonium. Ammonium is return to the environment when organic matter is degrade by heterotrophic microbes. Ammonium can become fixed inside clay mineral, which essentially traps the molecule and remove the ammonium from active cycling. Some of mineralized ammonium can discharge into the atmosphere because ammonium is volatile. Chemoautotrophic microbes can utilized an ammonium in a process identified as nitrification (Raina,

The word “remediate” means to solve a problem, so the word “bioremediation” refers to the use of biological organisms to solve an environmental problem. Bacteria, fungi, protists and other microorganisms in a non-polluted environment are constantly breaking down organic matter, and when the soil is polluted, some of the organisms may die, but others will still be able to break down the pollutants. Bioremediation provides organisms that can consume the pollutants with fertilizer, oxygen, and other conditions to encourage the rapid growth of these organisms. They then would be able to break down the organic pollutants at a correspondingly faster rate. There are two general ways in which bioremediation functions. One way is where specific survival conditions of a microorganism living in the soil are enhanced to increase the rate of a pollutant’s degradation. The second way is when specialized microbes are added to degrade the contaminant. This way is less common. For many types of polluted soil, bioremediation provides an excellent method of clean-up, but in some cases the pollutant is toxic even for the microbes. These pollutants include metals such as cadmium or lead, and salts such as sodium chloride. Although it may not work in all cases, bioremediation is considerably easier than other methods because it enhances the functions that the microbes already carry out in the soil. Along with being easier, it can be much less expensive because the soil does not have to be pumped out of the ground for treatment (Environmental Inquiry-Bioremediation). Serratia Marcescens is a bacterium that is commonly used for bioremediation.
within the soil. In this experiment, the liberation of ammonia is being employed as an indicator. Other components being utilized play a vital role in controlling the conditions of the experiment, as the THAM buffer, and the limitation of microbial activity, through toluene. The control experiment is crucial as it eliminates the addition of ammonia content being released by other sources within the soil into the final reading, providing accurate data.
Nitrogen fertilizers: firstly nitrogen is found in the air, so air is pumped into a large vessel. The air is warmed and oxygen is removed becoming steam. This leaves hydrogen, nitrogen and carbon dioxide. To remove the carbon dioxide an electric current is introduced into the system. And finally remains ammonia. Ammonia is further processed adding air to the solution and making nitric acid. In conclusion when ammonia and nitric acid are combined is made ammonium nitrate, the component used as fertilizers.
Cellular respiration and photosynthesis are important in the cycle of energy to withstand life as we define it. Cellular respiration and photosynthesis have several stages in where the making of energy occurs, and have diverse relationships with organelles within the eukaryotic cell. These processes are central in how life has evolved.
Air pollution is known to affect human and animal life. Plants are also affected indirectly as air pollution is known to cause acid rain, an even deeper detriment to plant life than most. Lung related diseases are among the most important features that the world have come
* Nitrogen Oxides are presented through the atmosphere. N2O are very powerful in the chemistry of the troposphere and the stratosphere, and they are very important in ozone production and in the destruction processes. There are a number of sources (the oxidation of N2O like lightning and fossil fuel combustion) whose contribution to NOx concentrations in the upper troposphere is not well measured.
Microbial decomposition releases nutrients into the environment that are needed by other organisms. Microbes are also involved in the cycling of many other important compounds in — and between — ecosystems, including oxygen, carbon and nitrogen. Many microbes use the energy of sunlight to convert carbon dioxide to oxygen, which we need to breathe. As they do this, they create new organic material — themselves — which are then eaten by other organisms. In this way, the cycling of nutrients and energy
furnaces. By letting all these gases release into the air, it makes it harder to breathe.
Air pollution according to the Wikipedia << is the introduction of particulates, biological materials, or other harmful materials into the Earth’s atmosphere, possibly causing disease, death to humans, damage to other living organisms such as food crops, or the natural or built environment>>. Therefore, human being should be aware of the facts that the environment and all living creatures are dying. They need to understand the importance of natural items, the nature, etc…
The Importance of Photosynthesis and What it Does for Life According to scientists, life is “the condition that distinguishes animals and plants from inorganic matter, including the capacity for growth, reproduction, functional activity, and continual change preceding death, also the way of life of a human being or animal. ”("Life,”) In order for one to have life, one must have the nine characteristics to be considered a living thing. These nine characteristics are: all living things are made up of cells, living things are able to reproduce, living things use energy, maintain homeostasis, respond and adapt to the environment, grow and develop, have a life span, evolve over time, and are interdependent. All of the nine characteristics have one thing in common, something that is needed for all living things to work, even if they do not know it.
Photosynthesis is the process in which living cells from plants and other organisms use sunlight to produce nutrients from carbon dioxide and water, the image below “Diagram of photosynthesis 1,” helps show this process. Photosynthesise generally creates oxygen as a by-product through the use of the green pigment, chlorophyll, found in the plant that helps this reaction occur. “Photosynthesis provides us with most of the oxygen we need in order to breathe. We, in turn, exhale the carbon dioxide needed by plants,” (factmonster,2017). This is able to show us why photosynthesis is so greatly needed to occur through plants in order to give one another essentials needed for continuity of life. “Plants perform photosynthesis because it generates the food and energy they need for growth and cellular respiration,” (photosynthesieeducation, 2016).
Air pollution is when a poisonous or harmful substance is released into the air. There are many forms of pollution but air is one of them, it only occurs when dust, harmful gases or smoke enters into the atmosphere and makes it hard for species like plants, animals and humans to live in a difficult situation because of the dirty air. Air Pollution is classified in two sections, invisible air pollution and visible air pollution.. Hence any substance that makes it difficult for the living things that need the atmosphere is air pollution. Humans have been undergoing air pollution ever since the industrial revolution.
For instance, ammonium nitrate used as ammonium nitrate fertilizer”. The philosophy of agriculture
...eochemical cycles. By increasing the amount of crops that are removed from the soil and the subsequent soil erosion, phosphorus levels in the soil have dropped. The phosphorus lost from the soils travels to aquatic ecosystems which then can cause massive algal blooms. The increased use of nitrogen based fertilizers has also altered that cycle. The fertilizers add high levels of nitrates to the soil, and in natural ecosystems, nitrates will undergo denitrification and be returned as atmospheric nitrogen. This is not the case because the nitrate levels exceed the levels of denitrification that bacteria can handle. Additionally, much of the denitrifying bacteria is found in marshes and wetlands, which are currently being destroyed at incredible rates. In some areas, the excess nitrate has made it into the ground water system and contaminated the drinking water system.
