Nutrient pollution coming from agricultural runoff and other fertilizers allows for the growth of species that upset the balance of the ecosystem such as Cattail, harmful algae bloom, and duckweed. The sulfur in the agricultural fertilizers leads to accumulation of toxic mercury in fish, birds, and mammals. Also, exotic animals or invasive species displaced native and threatens to disrupt the ecosystem balance. The purpose of this experiment is to determine how the water quality affects the Everglades ecosystem and how water pollution impacts different species. Urbanization is a big threat that contributes to poor water quality in water pollution.
Introduction Our aim of this experiment is to determine how eutrophication affects the growth of duckweed by adding different concentrations of fertilizers to the water with different types and forms of fertilizer keeping it in set conditions for a period of two months to observe how eutrophication affects the growth of duckweed. Thus our hypothesis for this aim is that it is expected that eutrophication would affect the growth of duckweed when different concentrations of fertilizers are added to the water. The reason for studying this aim is that we wish to see how eutrophication affects plant growth in the water even if fertilizers are added to the water. Literature Review The research question that we hope to answer is how eutrophication
I let the alcohol flow on 45-degree angle slide within 15 seconds and wash it with water to remove colors on the surface. Lastly, the unknown is once again dyed with safranin for 1 minute then wash it off with water for the last time and dry it using bibulous paper. After experiment on microscope under oil immersion, I learned that my Unknown is gram positive. Under the lens, the bacteria appears in purple color. Its morphology is cocci arranged in cluster.
Research Questions: What effect does acid rain have on the growth rate of plants in the wetland ecosystem? What results are expected? What is your conclusion? Hypothesis: Acid rain will have a negative impact on the plant growth in the wetland environment, this will result in plants dying and
The tube was placed back in incubation for 96 more hours to observe any more positives. 2.10 Catalase Test A trypticase soy agar plate was used and after incubation, four drops of 3% Hydrogen Peroxide was added to the plate to flow over the bacterial growth. A presence of bubbling was observed. 2.11 Starch Hydrolysis A starch agar plate was inoculated with a streak of the unknown bacteria and then incubated. On the second day of incubation, the plate was removed from the incubator and placed over a hot plate heating Iodine solids.
Nutrients are chemicals elements that plants and animals require for growth. Macro nutrients nitrogen, phosphorus, and potassium are found in artificial fertilizers. My neighbor would be affecting the nutrient cycle because the fertilizer is extracting nutrients from the soil and leaving them to be placed in the aquatic environment. This affects the Nutrient Cycle. When these nutrients are taken away this can lead to the soil lacking the micro nutrients that are needed.
One major way to improve this is to plant more deep-rooted plants to stop the water table from rising. Crops need different amount of water otherwise they might not grow but over watering the plant can cause the excess water to sweep into the soil and raise the ground water which will raise the chances of salinity occurring in that area. Every year a large space in the Murray Darling Basin loses a large area of farming land to salinity because of over-watering plants. There is a way to see when salinity may occur in farming fields as the plants height, the number of leaves and shoots all decrease; generally, plants response to salinity. If salinity as occurred in that area, wilted plant and leaf burn would be shown on the plant/s salinity affected.
The livestock industry depends on the rangeland for forage. With past mismanagement of rangeland overgrazing, and soil erosion have put enormous pressure on us to make rangeland conservation a priority. The primary objective for rangeland management is the long-term maximization of livestock productivity from managed rangeland. Grazing capacity needs to be considered for the planned management of the
ENP provides plants and animals with the resources that they need. The park provides many habitats where flora and fauna thrive, such as sawgrass prairies, freshwater sloughs, pine rocklands, estuaries, and hardwood hammocks. These habitats have been altered by many factors including human impacts, hurricanes, non-native species, water quality issues, water quantity issues, wildland fires, etc. (“Environmental Factors”). These factors are the main culprits that are causing the degradation of the park.
As mentioned in an article named, “Causes of Drought: What 's the Climate Connection?” different types of droughts and how they are created is explained. It is mentioned that “agricultural droughts can occur for a variety of reasons, including low precipitation, the timing of water availability, or decreased access to water supplies” (UCSUSA). All of these aspects are affected by climate change, therefore, increasing the risks of droughts. Water is a vital source for agriculture; in fact, many of the world’s water supply already goes to agriculture. To be specific, 70% of fresh water goes to agriculture and this can increase up to 90% in drier regions (Gilman).
