Therefore, we need to keep it clean at every point in the global water cycle. The water cycle starts when water is evaporated from water sources, such as rivers, lakes, streams, and oceans. The evaporated water rises into the atmosphere to form clouds. Then the water particles in the clouds condense and fall to the…

  • Phosphorus Cycle Essay

    Explain how human activities can cause an imbalance in biogeochemical cycling and lead to problems such as cultural eutrophication and fish kills. Biogeochemical cycling is defined as the chemical element flow between the living and nonliving components of the ecosystem. This is the cycle of nitrogen, phosphorus and carbon being converted into organic substances of plants and animals that are released back into the environment.

  • How Does Chlorophyll Affect Plant Growth

    Introduction: Once a plant begins growth, it depends on multiple abiotic factors to continue growing: light, carbon dioxide and water. These three factors affect the growth rate of a plant, causing it to grow quicker or slower. Furthermore, altering these factors may stunt plants growth or improve it. For example, plants require an adequate amount of water to survive. Water hydrates the plant and also breaks down the minerals in the soil. As the plant absorbs the water, nutrients are transported…

  • Conservation Of Water Pollution Essay

    chemicals can cause an abundance of algae to emerge, leading to oxygen deprivation in the area (Manuel 6). In addition to a depleted amount of oxygen, industrial wastes like phosphates cause eutrophication, or "the aging of a lake by enrichment of its water" (“Eutrophication” 1). In the natural cycle of eutrophication, water will disappear after thousands of years. However, chemicals significantly speed up the process by stripping away essential nutrients, such as oxygen, from marine life and…

  • The Phosphorus Cycle

    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…
