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.
Some of the dissolved carbon dioxide remains in the water, the warmer the water the less carbon dioxide remains in the water. Some carbon dioxide is used by algae and phytoplankton through the process of photosynthesis. In the natural carbon cycle, there are two main processes which occur: * Photosynthesis = plants use carbon dioxide and produce oxygen. * Metabolism = oxygen is used and carbon dioxide is a product Humans impact the carbon cycle during the combustion of any type of fossil fuel, which may include oil, coal, or natural gas. Fossil Fuels were formed very long ago from plant or animal remains that were buried, compressed, and transformed into oil, coal, or natural gas.
Phosphorus Cycle The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere. Unlike many other biogeochemical cycles, the atmosphere does not play a significant role in the movement of phosphorus, because phosphorus and phosphorus-based compounds are usually solids at the typical ranges of temperature and pressure found on Earth. The production of phosphine gas occurs only in specialized, local conditions. Low phosphorus (chemical symbol, P) availability slows down microbial growth, which has been shown in studies of soil microbial biomass. Soil microorganisms act as sinks and sources of available P in the biogeochemical cycle.
Some simply drain off into lakes and oceans and become lost in sediments. Phosphate loss is not serious because new phosphates continually enter the environment from other sources. The Phosphorus Cycle Phosphates come from fertilizers, pesticides, industry, and cleaning compounds. Natural sources include phosphate-containing rocks and solid or liquid wastes. Phosphates enter waterways from human and animal wastes (the human body releases about a pound of phosphorus per year), phosphate-rich rocks, wastes from laundries, cleaning and industrial processes, and farm fertilizers.
For instance Carbon Dioxide from the atmosphere is synthesized by plants, which is ingested and metabolized by animals, which is converted to Carbon Dioxide during respiration and decay. Humans remove over 40% of the photosynthetic that effort plants in order to support human enterprises. When humans burn fossils fuels that increases the atmosphere Carbon Dioxide by 35%, then during the combustion stage the present of air (oxygen), Carbon Dioxide and water molecules are release into the atmosphere. Human has an impact on the Phosphorus Cycle as well as the Carbon Cycle. 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.
Recycling of phosphorus is environmentally important because absorbed nutrient becomes available for plants in the form of fertilizer and the water quality becomes better for people’s use (Sigee, 2005). Before nutrients, especially phosphate will be removed from wastewater, sewage will go through other stages of treatment. The first step is primary treatment of sewage, where large solid materials (rags, wood, fecal material), settle able solids and pathogens are removed. The secondary treatment process aims to reduce organic material and heterotrophic bacteria that utilize the organic compound for growth and energy. And the last step is tertiary treatment, where all organic ions, particularly ammonium, nitrate, and phosphate are removed (Abdel-Raouf et al., 2012; de-Bashan & Bashan, 2004).
A two-way catalytic converter has similar functions. A two-way catalytic converter eliminates the first task of decomposing nitrogen oxide, resulting in a more harmful emission. There are many negative aspects to catalytic converters. A main controversy of a catalytic converter is that it only works at very high temperatures. For the first few minutes when a car is started or warming up, toxic chemicals
What are the three trophic levels? There are three trophic levels in our ecosystem. The first trophic level is Producers: Organisms that capture energy from the sun or chemical reactions to convert carbon dioxide to organic matter; most producers are green plants. (Boorse,Wright,2011) The second trophic level is Consumers which are organisms that derive their energy from feeding on other organisms or their products. (Boorse, Wright, 2011) The third trophic level is Decomposers, these organisms feeding actions are a result of rotting or organic material.
The basis of gasification is to supply less oxidant than would be required for stoichiometric combustion of a solid fuel. Stoichiometric combustion occurs when all the carbon in the fuel is converted to CO2 and there is no excess O2 left over. Doherty, W. et al (2009) noted that the energy value of the useful gas is typically 75% of the chemical heating value of the original solid fuel and the syngas temperature will be substantially higher than the original solid fuel due to the gasification process. 2.8.5 Landfill gas (LFG) collection and utilization Landfills produce landfill gas by the degradation of organic matter under anaerobic conditions. The evaluation of any landfill gas recovery project is highly effected by the composition of waste, specifically the organic fraction, moisture level, and the “degradation” factor of different waste components.
Instead they use a process known as chemosynthesis. Bacteria use energy from hydrogen sulphide to join water and carbon dioxide to make carbohydrates. Food chains survive based on these bacteria. What could happen without solar radiation? Life on earth with less solar radiation can decrease support for producers.
