Decomposition of Leaf Litter in Aquatic System
Name: Aisha Ali Ahmed Al-Khan ID:90165
-----------------------------------------------------------------------------------------

Introduction
Leaf litter is important for many organisms. It provides nesting materials, microhabitat for microorganism and provides protection. Bacteria, fungi and some invertebrates in the leaf litter benefit by feed on it and using them as shelters. Microorganisms play role in breaking leaf litter into small parts and make it is easy for decomposition. Aquatic systems lakes show major inputs from autochthonous sources. It is difficult to determine how much primary producers; allochthonous and autochthonous play role in organic deposits as the diverse inputs such as dead organic material with attached microorganisms, result in complex mixture accumulating heterogeneously in the bottom of the aquatic system. …show more content…

Some features affect negatively on the decomposition rate such as; lignin, tannins, nitrogen ratio and hardness of the leaf surface.
This paper reports an experiment of leaf decomposition rates for two species; Conocarpus erectus and Albizia lebbeck. It tests the hypothesis that decomposition rate of leaf litter affected by the leaf characteristics and other biological factors such as invertebrates, fungi and

Eutrophication, which is excessive richness of nutrients in any form of body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen, is another reason why the creek could be polluted. Fertilizers are used in farming to provide crops with nutrients, but they also play a big role in the Eutrophication process. If too much fertilizer is used, it leaches from the soil in

One issue found is the creation of smelly phytoplankton that makes murky unclear waters along with aquatic impurities. Moreover, the reduction of growth due to poor light conditions and dying plants make it difficult for predatory fish to hunt leading to overpopulation. (Chislock, 2013) Eutrophication can be found in many of our water resources such as ponds, estuaries, and bays. One region with high areas with eutrophication is in a lake shared by Kisumu, Kenya and Kampala, Uganda.

Lab Report- Penny Drop Lab Abstract: This lab is called the Penny Drop Lab. In this lab, your goal is to find out how many drops of water you can fit on the top surface of a penny. You are trying to find the surface tension between two liquids. In this case, we used soapy water and plain water. Adding soap ends up reducing the surface tension of the water.

Eutrophication is the excessive nutrients in a lake or body of water, frequently due to runoff from the land, which causes a dense growth of a plant life and death of animal life from lack of oxygen. We tested for phosphate, nitrate, and dissolved oxygen. Phosphates and Nitrates are found in fertilizers, laundry detergents, and sewage treatments. Dissolved oxygen is microscopic bubbles of gaseous oxygen that are mixed in water and aailable to aquatic organisms for respiration. We found that there was a phosphate average of 0.1 parts per million (ppm).

Lars Eighner goes into great detail in his essay, “On Dumpster Diving”, when discussing about his experiences living on the streets and the ways of Dumpster diving. He called himself a “scavenger” and even though he would rather live a “comfortable consumer life,” he learned so much from being a scavenger. Eighner begins the chapter with the three principles; what is safe to consume, knowing the Dumpsters, and knowing the answer to the question “Why was this discarded?” He then discusses how to identify good or rotten foods; what will leave the person satisfied or have the person end up with botulism. Eighner also states the benefits of knowing the different locations of dumpsters, like his experience with the Dumpster behind a pizza delivery shop.

In the text "On Dumpster Diving," Lars Eighner gives us an inside depth of what it's like being homeless and having to dumpster dive for living. Lars Eighner shows how dumpster diving has become a full-time job because it's the only way he can survive. Eighner claims that dumpster diving requires a lot of effort, he made some rules that would help others in the same situation become more efficient and find supplies that are useful for their survival. Dumpster diving has helped Eighner realize that materialistic things aren't necessary and that you should live off necessity. Eighner used to invest on materials that weren't necessary, but dumpster diving has helped him find value in his life and it helped him realize that people need must be grateful for what they have.

Leah Romero 10/30/2017 Conclusion Lab 3 Chem 102L In lab 3, fundamentals of chromatography, the purpose was to examine how components of mixtures can be separated by taking advantage of different in physical properties. A huge process in this lab was paper chromatography, which was used to isolate food dyes that are found in different drink mixes. The different chromatograms of FD&C dyes were compared to identify which dyes are present in each of the mixes.

Wasteland is a documentary by Lucy Walker that depicts the lives of selected garbage pickers in Jardim Gramacho – a massive dumpsite found in the outskirts of Rio de Janeiro. The film is about Vik Muniz’s 2-year journey back to his home country seeking to give back to an impoverished community through making images out of an unusual material – trash. The film featured 7 garbage pickers from the landfill, and each has a story that brought them to their current places. One unique thing about the whole creative process is that the pickers themselves became part of it. Vik imagined that as they work on their own and each other’s images, the pickers will not only show themselves to a broader world that is for now comfortably oblivious of their existence, but also see themselves differently (Fuchs, 2010).

The purpose of this lab was to test the effect of pollution on algae growth. Through a series of experiments that lasted a month, four of the six hypotheses were proven to be correct or partially correct. The first hypothesis stated that if 0.5 mL of salt was added to algae, then the algae would grow slower than the positive control. This was proven correct, as shown by the difference of the data from the positive control and the container with 0.5 mL of salt in it.

Nowadays debris is an integral part of humanity life. Mankind thinks about how to make the product easier and cheaper to use, but nobody cares what happens with waste after it was used. We contaminate the environment with every decade increasingly: muddied air and water, global warming are an output of human life. The worst thing is that from such attitude other living beings are dying. Millions of animals and birds cannot withstand such environmental changes; their populations become smaller and, eventually, disappear altogether from the face of the earth.

The ocean is nowadays undergoing numerous environmental issues that further lead to marine pollution. Marine pollution is a very serious environmental issue that most of the countries of the world encounter. Aquatic littering is considered as one of the major causes of marine environment. The misleading use of the marine environment is extremely impacting the marine life and ecosystems. Moreover, the total amount of toxins and debris discharged by human beings is incredibly increasing in today 's world.

Sustainable forest management requires three major criteria which are the maintenance of ecological processes within the forest (soil formation, energy flow, biogeochemical cycles (carbon, nutrient and hydrological cycles), maintenance of biodiversity of forest, improving the net social benefits derived from the mixture of forest uses within the constraints by considering the future. Forest provides habitats for more than half of the fauna and flora on the Earth (SCBD, 2001). Forest biome plays an important role in mitigating climate change by serving as carbon sinks (Hassan et al., 2005). Forest land is the most fundamental natural resources which become reduced mainly due to anthropogenic pressures. For proper management of land, it is essential to have information about existing land cover and about the naturalness of the land.
