The Nitrogen Cycle Name: Isabelle Rowe Go to the following website: http://nortonbooks.com/college/biology/animations/ch38a02.htm 1. What are the 2 forms of usable nitrogen? The two forms of usable of nitrogen are ammonium and nitrates. 2. What is the term used for this conversion process? This conversion of N2 (nitrogen) into NH4+ (ammonium) and NO3- (nitrate) is called nitrogen fixation. 3. Much of nitrogen fixation by humans is done by what? Most of nitrogen fixation done

Nitrogen Nitrogen is an element, in which its name is derived from the Latin word ‘nitrum’ known to be the fifth most abundant element in the universe. Nitrogen is one of the building blocks of life; living organisms may cease to exist without the existence of nitrogen. It can be said that nitrogen makes up of 80 percent of our atmosphere. It has an atomic number of 7 and is located in the far left of the periodic table. The element belongs to Group 15, Period 2 and p Block and has an electronic

There are 3 different main cycles. There 's the nitrogen cycle , water cycle , carbon cycle. They work together by carrying away waste and restoring the ecosystem with nutrients that are necessary to sustain life. These three cycles help the world function to produce air, water , and nutrients. If any of these three cycles were to become unbalanced , the effects on the ecosystem would be catastrophic. The Water Cycle is the cycle of process by which water circulates between the earth

Fritz Haber, born on December 9, 1868 was a German physical chemist who greatly shaped the world. Considered to be the "father of chemical warfare" for his years of pioneering poisonous gases during World War I, it is easy for one to forget Haber’s positive contributions to the science industry. Despite the lack of moral of Fritz Haber’s character, he was brilliant and ambitious and his ideas have indeed made the world a better place. First and foremost, Haber is credited with creating a process

The purpose of the Plant Mineral Nutrition Lab was to grow Helianthus annuus plants also known as sunflower seeds in order to see the effects that nitrogen has on its growth. The first week, Helianthus annuus seeds were planted into a perlite. A week later, a beaker was given and the stock solutions for high nitrogen was used. In order for high nitrogen, the eight stock solutions were doubled. After the right amount of stock solutions was added, distilled water was added to reach the final volume

Chemistry of Fireworks Fireworks rely on chemistry in terms of their principles of combustion, reduction and oxidation reactions, and the excitement of electrons. Fireworks have been popular for an immensely long time. Fireworks were invented in the 12th century by the chinese. A alchemist accidentally discovered black powder by mixing sulfur, potassium nitrate, and charcoal (form of carbon). He soon realized that this combination of elements was extremely flammable and explosive. Black powder

through pH, nitrogen, phosphorous, and dissolved oxygen. pH levels are the levels of acidity or alkaline found in the water. Low pH levels (under 7.0) mean that the water is too acidic. High pH levels (over 7.0) mean greater alkaline level. A pH range of 6.5 - 8.5 is a safe range for aquatic life. Nitrogen and phosphorus are elements in the water that support the life of underwater plants. If the levels are too high (over 3.0), this is dangerous for aquatic animals. If the nitrogen and phosphorus

Agriculture affects every aspect of an ecosystem including people, animals, flora, and the environment. In fact, “agriculture contributes 42 percent of the nitrogen, 55 percent of the phosphorous, and 60 percent of the sediment entering the Bay” (Chesapeake Bay Program). However, consumers in Maryland hold a say in whether these effects are positive or negative depending on whether they buy organic or nonorganic foods. The United States Department of Agriculture (USDA) only certify foods as “USDA

Urea cycle Introduction The task of urea cycle is to avoid the amassing of toxic NH4+. It incorporates nitrogen not used for biosynthetic purposes into urea, which serve as the waste nitrogen produce in mammals. Urea is the major disposal form of amino groups derived from amino acids, and account for about 90% of the nitrogen-containing gears of urine. Also urea cycle is accountable for de novo synthesis of arginine. The complete Urea Cycle is by far only in liver. However, some enzymes of the

Yasmin Givens Introduction The purpose of this experiment is to investigate the effects and results of agricultural runoff, as well as how varying types of fertilizer (conventional and time-released) may affect the ever-growing problem of eutrophication. If the conditions of agricultural runoff are simulated, then the algae will grow plentifully and consequently kill the other life in the water. If the different types of fertilizer are tested (conventional and time released), then the time released

Amanda Kranning October 27, 2015 Eutrophication is a syndrome of ecosystem responses to human activities that fertilize water bodies with nitrogen (N) and phosphorus (P), often leading to changes in animal and plant populations and degradation of water and habitat quality.(Cloern, Krantz, & Hogan, 2013) Eutrophication forms when an abundance of nitrogen and phosphorus increases growth within an environment. One issue found is the creation of smelly phytoplankton that makes murky unclear waters

between the fertilizer and the microorganisms. According to Good and Beatty nitrogen is found in fertilizer and when the nitrogen is added to the aquatic ecosystem it will cause a flourishing of microbial growth, which can result in a “dead zone” (2). I hypothesized that the more fertilizer added to the Susan’s Swamp solutions, the more microorganisms I would find, because of the nutritional properties in fertilizer such as nitrogen. Methods: In this experiment four samples from Susan’s Swamp were collected

Plants for their growth absorb both nitrates and phosphates. Nitrates are a compound of nitrogen and phosphates are phosphorus compounds, most are produced by bacteria. The human use of detergents and chemical fertilizers has swiftly increased the amount of nitrates and phosphates that are washed into lakes. As this process occurs, the growth

These fertilizers contain high levels of Nitrogen; these are very effective and important nutrients for plant growth. Other Non-Organic fertilizers that are in much use in agriculture are like Nitrogen fertilizers, Potassium fertilizers, and Phosphorus fertilizers. Nitrogen fertilizers come in several different types, for example, Ammonium Nitrate, Potassium Nitrate, Calcium Nitrate and Urea. These fertilizers have very high levels of nitrogen, which is the most important nutrients for plant

The Phosphorous Cycle within the Earths Spheres The main component of the phosphorous cycle is soil. This means that the sphere, lithosphere which includes soil is the most important sphere including biosphere which also has a part in the cycle. This is because the plants and animals are the main components, which keeps the cycle going through the stages needed for it to be completed and to occur again. The Phosphorous cycle is essential for every living organism’s in the biosphere, supplying cells

Explain how the abundance of phytoplankton in the pond depends on the abundance of an abiotic resource such as nitrogen. - Phytoplankton are the producers in the pond. Species of organisms in ecosystems have their own carrying capacity relative to other species, and carrying capacities are determined by particular abiotic and biotic resources in an ecosystem. An increase in nitrogen levels in the pond (e.g. from fertilizers) will result in a dramatic increase in phytoplankton levels, but once phytoplankton

fix atmospheric nitrogen gas into a more usable form such as ammonia. A diazotroph is an organism that is able to grow without external sources of fixed nitrogen. Examples of organisms that do this are rhizobia and Frankia (in symbiosis) and Azospirillum. Types Of Diazotroph? Diazotroph are across bacterial taxonomic group (mostly in the bacteria and archaea). With a specific that can fix nitrogen may be strain do not fix nitrogen. Fixation is shut off when other sources of nitrogen are available

Seeds. Nitrogen, along with oxygen, is a necessary element for living organisms. Nitrogen makes up over seventy-eight percent of the atmosphere, and without it, life would not be feasible on planet Earth. Nitrogen partly makes up protein, and without protein, cells will lack proper nourishment to repair or build new tissues. Apart from humans and animals, plants satisfy their nitrogen requirements by absorbing ammonium or nitrate from soil water, which is needed for their growth. While nitrogen is important

1 – Denitrification Denitrification is the process that converts nitrate to nitrogen gas, thus removing bioavailable nitrogen and returning it to the atmosphere. Dinitrogen gas (N2) is the ultimate end product of denitrification, but other intermediate gaseous forms of nitrogen exist (Figure 7). Some of these gases, such as nitrous oxide (N2O), are considered greenhouse gasses, reacting with ozone and contributing to air pollution. Unlike nitrification, denitrification is an anaerobic process, occurring

1. Introduction Phosphorus (P) is vital for the growth of plants and is the second major macro-element after nitrogen, which limits plant growth (Gyaneshwar et al., 2002). Most of the soluble inorganic phosphate is applied annually to the soil as a chemical fertilizer, which is immobilized quickly and again becomes inaccessible to plants. Hence, the lower amount of soluble P in soil is one of the limiting factors for agronomic crop production. Fertilizers (microbial inoculant) offer a solution, as
