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.
Sand is mostly made of material grains. According to the University of Illinois, “a garden with sandy soil has very little water and nutrient retention,” this will cause the decomposition to occur very slowly. By putting air holes in the top of the container lid it is allowing oxygen to circulate through all of the environments. After the apple has fully decomposed in the soil compost is made. The Webster Dictionary’s definition of compost is, “a mixture that consists largely of decayed organic matter and is used for fertilizing and conditioning land.” Compost is improves the soils structure and helps keep in air, nutrients, and moisture for the plants growing in the compost.

Though they provide no amount of energy, they are required for the normal growth, maintenance and functioning of the human body. They are important constituents in considering quality aspects of food quality. Vitamin losses can occur through chemical reactions which lead to inactive products.
Tube 2 also seen an increase in the reaction and color intensity. Tube 3, the one with no catecholase had none or very little reaction. Introduction: Enzymes are macromolecules serving as a catalyst, or a chemical agent that changes the rate of a reaction without being consumed by the reaction. Catecholase has an optimum level of ph between 6-8. There are some exceptions like Pepsin, a Digestive Enzyme which has a Ph of 2, which is found in the stomach of humans.
Manganese dioxide is an inorganic molecule that can achieve this. The catalyst lowers the activation energy of the decomposition which is already noticeable without the addition of a catalyst. In our lab we observed that the Manganse dioxide had no effect on the reaction, however it should have a significant
Also phosphorus is in are detergent’s and fertilizers. Nitrogen is a bacterium that’s in a root of any living plants. The nitrogen cycle is similarities with both phosphorus and carbon cycle. Nitrogen and carbon produces gas and nitrogen and phosphorus produces a high demand of aquatic. Human’s impacts the nitrogen by their crops from using fertilizers which damage the root’s and cause bacteria.
Runoff of chemical fertilizers, animal waste and pesticides contaminates lakes and streams. Excessive amounts of nitrogen and phosphorus in the water can cause algal blooms and result in ocean dead zones such as the one in the Gulf of Mexico." Foods that are shipped from a distance are usually filled with preservatives that way they stay good on the trip and for a little while on the
Hydropower plays a major role in reducing greenhouse gas emissions which could also help with less pollution released into the environment. Hydroelectricity requires relatively low operations and maintenance costs. This is very beneficial today since the economy is bad and that we have had a bad president for the past eight years. Lastly, it's renewable - rainfall renews the water in the reservoir, so the fuel is almost always there. The disadvantages of hydroelectric power are high investment costs, hydrology dependent (precipitation), and fish entrainment or passage restriction.
This limits aquatic life, which reduces the supply of fish. Current policies are primarily aimed at reducing waste disposal into rivers and reduction of nitrogen and phosphorous use. These policies are subject to various issues such as increased food prices and complexity in the understanding of the true relationship between algae and nutrients. Therefore, the policies have not been effective. It is important to research on ways of controlling draught and limiting algae growth because it will mitigate further expansion of the Gulf of Dead Zone.
Science, Health, and Environmental Issues Pamela Ward Eng122: English Composition 2 Prof. Iris Chao October 27, 2013 Phosphates and Nitrates Phosphates and Nitrates are chemicals commonly found in water. Even though they are not harmful in small quantities, they are harmful if they exist in large quantities. Farms use fertilizers containing large amounts of nitrates and phosphates, so they can build up water near industrial-scale farms. In a body of water in which nitrate levels have risen to high levels, these chemicals can cause excessive algae growth. When the algae die and decompose, they deplete the available oxygen in the water for fish, causing them to die.
