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…

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…

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…

The most likely causes for the dead zone in the Great Lakes are the amount of phosphorus nitrogen and fertilizer running off into the lake. When the lake becomes rich in these nutrients and you add warmer temperatures into the equation you can expect an algal bloom. Once the bloom dies the decomposition depletes much of the oxygen in the water which is severe because of the size of the algal bloom. This coupled with things such as low water inflow and temperature of water are the most popularly…

English chemist.(It’s Elemental- The Element Argon) These two chemists weren’t actually trying to discover this element. Stated at Argon- Element information, properties and uses | Periodic Table, they actually were trying to explain the density of nitrogen from air differed from that obtained by the decomposition of ammonia. It just so happened while they were trying to explain their theory they were able to discover the element Argon. Argon can be found in nature in a very little amount.…

Agricultural bacteria, fertilizers and manure that is distributed throughout fields causes a rise in the groundwater’s concentration that exceeds the max containment level for intake. These excess levels of nitrate found in water are extremely hard on the human body, and can be lethal in infants (Holme). Mixing water with formula to feed a baby is a perfect example of how nitrites can enter an infant’s immature digestive system. In 1999, a 3-week old in Wisconsin suffered from…

convert the nitrate to nitrogen that can be released into the atmosphere as gas. However, the scientists found a shocking result that the bacteria have only been eliminating 16% of all nitrogen pollution (Futurism). This is a matter that must be addressed, considering the percentages may drop lower over time. This oppression of nutrients has caused many complications and damage to our…

Discussion The cleanliness of tap water is determined by comparing many different factors of the water’s composition to the acceptable or ideal levels that have been set for “healthy” water. The water samples from each city show that the tap water remains within an acceptable range. For instance, the acceptable level for Nitrate in water is 10 ppm, a maximum level enforced by the Environmental Protection Agency, and each city did not exceed that amount with the highest level being 5 ppm in one…
