Nitrogen cycle

Unit 2 Project In your own words Discuss why carbon is essential to life on Earth. (150 word minimum response) Carbon is a vital element in organic compounds. Organic compounds are compounds that are usually located in living things.Organic compounds are very vital and Carbon is an elemnt that makes up organic compounds. Carbon helps organic compounds make up cells and carry out important life functions.Additionally, carbon can form strong bonds with itself and many other elements. This…

The aim of this experiment was to determine the percentage composition of magnesium and oxygen in magnesium oxide and evaluate if the composition varies or remains constant. To test this, magnesium was heated and made to react with the oxygen gas in the atmosphere. This reaction formed the ionic compound, magnesium oxide. The percentage composition was later calculated based on the results of the experiment as shown in the above calculations, Figure 4. These results were compared to the expected…

The results of activity concentrations of the 226Ra, 232Th and40K in the Palm Date Pits samples has been presented in Table 5. In Table 5, the mean activity concentrations of 226Ra, 232Th, and 40K in Palm Date Pits samples are 5.684 ± 1.238, 2.790 ± 0.457, 181.090 ± 16.804 Bqkg-1, ranging from 1.343 ± 0.380 to 14.526 ± 3.932 Bqkg-1, 1.420 ± 0.322 to 6.379 ± 0.368 Bqkg-1 and 89.554 ± 9.621 to 252.242 ± 12.234 Bqkg-1, respectively. The high variation in activity concentrations of 226Ra, 232Th and…

In ecology, interspecific competition occurs between two different species that compete for the same resources (Connell, 1983). These resources include sunlight, water, nutrients, space and mates (Connell, 1983). Interspecific competition can lead to reduced fitness of one or both of the species, as resources of the ecosystem become limited (Connell, 1983). In this study, the effects of interspecific competition were compared between Cynodon dactylon (Bermuda grass) and Calyptocarpus vialis…

The phosphorus cycle is the movement of phosphorus in the ecosystem. The cycle starts from the rocks which contain a lot of phosphorus compounds. As these rocks experience weathering, they break down and gets mixed into the ground. Sometimes it gets washed away in water. With this, plants are able to absorb P from the ground. The animals eat these plants and absorb P. The phosphorus returns to the soil through the wastes we release, and when the dead decompose. These then goes back to the…

how it interacts with herbicides. The lab showed the participants on a small scale how eutrophication occurs and how it doesn't take a long time for algae to take over an area. Nitrogen and Phosphorus are usually found in fertilizers but not always at the same time. A study done said “ Concentrations of phosphorus and nitrogen in surface waters are being regulated in the United States and European Union. Human activity has raised the concentrations of these nutrients, leading to eutrophication…

Generally nitrogen levels are low in unpolluted water but can be found in small amounts. Determining the presence of nitrate can be difficult due to the small amounts of nitrate in water. Nitrate can be found in rivers lakes and ground water. Nitrate nitrogen is the pre dominant form of nitrogen. A high level of nitrate present in water indicates that there was organic pollution but not recently. Plants and animals need nutrients like nitrogen for the formation of amino acids. Nitrogen cannot…

Nitrogen-fixing bacteria are microorganisms present in the soil or in plant roots that change nitrogen gases from the atmosphere into solid nitrogen compounds that plants can use in the soil. Let's break this concept down. Nitrogen is commonly found as an inert, or nonreactive, gas in the Earth's atmosphere. In fact, 78% of the Earth's atmosphere is nitrogen in its gaseous design. This element is so sufficient that it has been incorporated into all living things on Earth. In order for this to…

How gunpowder changed warfare How gunpowder was invented is that some scientists in china were experimenting Saltpeter a powerful agent potassium nitrate. It was used in medical compounds for years until a man thought about mixing the potassium agent with sulfur and charcoal, it had a result of a mysterious powder. Some observers said that smoke and fire the scientist’s body parts were burnt and the houses that they were working at burnt down too. The powder was used by the reigning Sung…

People drinking water for many years that contains higher MCL for atrazine can suffer from cardiovascular or reproductive diseases. Also, it has ecological effects on birds and aquatic organisms, although it is only slightly toxic to birds and fishes found in those niches. Atrazine also inhibits photosynthesis in plants. In 1974, Congress passed the Safe Drinking Water Act. This law requires EPA to determine the level of contaminants in drinking water at which no adverse health effects are…
