The Phosphorus Cycle is representative of the cycle of all biologically important mineral nutrients-those elements that have their origin in the rock and soil minerals of the Lithosphere, such as iron, calcium, and potassium. Humans have a serious intrusion into the Phosphorus Cycle that comes from the use of Phosphorus Cycle that contains fertilizers. Phosphorus is mined all around the world then made into fertilizers, animal feeds, detergents and other products. (Wright & Boorse) The third cycle that Humans impact in the Ecosystem is the Nitrogen Cycle. The Nitrogen Cycle is the process by which Nitrogen is converted between its various chemical forms.
Phosphorus enters the environment from rocks or deposits laid down on the earth many years ago. The phosphate rock is commercially available form is called apatite. Other deposits may be from fossilized bone or bird droppings called guano. Weathering and erosion of rocks gradually releases phosphorus as phosphate ions which are soluble in water. Land plants need phosphate as a fertilizer or nutrient.
Inorganic ions are charged particles that do not contain carbon atoms bonded together. While organisms are mainly built from carbon-containing molecules, their functions rely on inorganic ions such as nitrate, hydrogen and calcium. This essay will detail some of the roles of specific ions and describe how animals, plants and bacteria use them. Productivity in an ecosystem in the soil is limited in part by the availability of fixed nitrogen in the soil. Nitrogen fixing bacteria in the roots of leguminous plants reduce atmospheric nitrogen to ammonium using ATP and reduced NAD.
Phosphorus is a limiting nutrient for aquatic organisms. Phosphorus forms parts of important life-sustaining molecules that are very common in the biosphere. Phosphorus does not enter the atmosphere, remaining mostly on land and in rock and soil minerals. Eighty percent of the mined phosphorus is used to make fertilizers, and a type of phosphorus such as dilute phosphoric acid is used in soft drinks. Phosphates may be effective in such ways but also causes pollution issues in lakes and streams.
Some of runoff enters rivers flowing water towards ocean where water cycle had started. Another cycle which is part of the ecosystem is the nitrogen cycle. All living organisms require a source of nitrogen from which to manufacture proteins, nucleic acids and other nitrogen containing compounds. Plants take up most of nitrogen they need in form of nitrate (NO3- ) ions from the soil. Ammonification is the production of ammonia from organic compounds such as urea.
The scientists proved that carbon-14, which is present in our atmosphere as carbon dioxide, is absorbed by plants, animals, and human beings at a constant rate, and that the amount of carbon-14 is stabilized at a specific amount. A living organism can only intake a finite amount of carbon-14. Then, at the moment the living organism dies, it stops taking in any carbon-14, and the carbon-14 remaining in the organism starts to disintegrate at the half-life rate of 5,568 years (Poole 1961:27). (Today, based on refined calculations/techniques the half-life rate of carbon-14
When glucose polymerises to become cellulose, water is eliminated and the structure becomes: The H and OH groups are omitted for clarity. It must noted that: for bonding to occur, alternate glucose units must be inverted as shown above; this bonding produces a very linear molecule due to the geometry of the rings and the C-O-C angles. * Biomass – material produced by living organisms, mainly it is plant material though it also includes animal excreta and algae material. Cellulose is the major component of plant biomass. * Cellulose as a source of chemicals – starch, another polymer of glucose, can be used as an alternative source for petrochemical products but there is more cellulose produced in plants than starch.
The microbes eat the soil compounds, therefore converting them into a form plants can actually use. Although it must be known which calcium compounds are needed by the microbes in the soil for this to actually be put into progress successfully, this is the only way plants can actually than receive their desired calcium.1 ------------------------------------------------- Calcium acetate is one of the many minerals needed to drive metabolic reactions in plants. Calcium acetate is an important component in the formation of the pigment chlorophyll - which is essential for capturing light in photosynthesis. When Calcium acetate is not available to the plant, chlorosis occurs, resulting in purple and brown leaves that no longer provide energy to the plant, resulting in cell death.1 ------------------------------------------------- This dependence on Calcium acetate for everyday biological function is best demonstrated in its absence: Calcium deficiency leads to 4% of all child mortalities or significantly shortened life spans in humans. While this trace
How carbon in the atmosphere is added to rocks and is gone back through the atmosphere? The movement of carbon between the atmosphere and the lithosphere (rocks) begins with rain. This is where atmospheric carbon combines with water to form a weak acid – carbonic acid – that falls to the surface in rain. The acid dissolves rocks – a process called chemical weathering – and releases calcium, magnesium, potassium, or sodium ions. The rivers then carry the ions on to the sea.
Fats containing unsaturated fatty acids are liquid at room temperature such as ground-nut oil, musturd oil etc, Proteins- The proteins are highly complex organic compounds of carbon, hydrogen, oxygen and nitrogen. Proteins are made up of nitrogen containing compounds called amino acids, Proteins are very Important for the growth and repair of the body. Kwashiorkar is a disease which occurs due to the deficiency of proteins In the diet of children. Whereas Marasmus occurs in the Infants (small children) due to the deficiency of proteins, Minerals- The metals, non-metals and their salts are called minerals. Our body needs minerals for its proper
