Topic:ResponsesSubject:BiologySources:-Style:APA 7th edition
Please read those responses and write a paragraph in response to it, it needs to be value-added or comment. The response should further the thread topics; show that you have learned something from our readings or outside research; bring anecdotal, life experiences to the threaded issues; 4 ask relevant and forward-moving questions, or otherwise promote the Course Objectives for the week. Examples of high-quality posts include: providing additional information to the discussion; elaborating on previous comments from others; presenting explanations of concepts or methods to help fellow students, presenting reasons for or against a topic in a persuasive fashion, sharing your own personal experiences that relate to the topic, and providing a URL and explanation for an area you researched on the Internet. (NO WIKIS as an internet source). But most of all no plagiarism. Make the responses about those two paragraphs there and if you have any questions just ask me. For each make a 1 paragraph response.
1. Hi Professor and Class, Bioelements need the process of recycling as if there wasn’t recycling going on then it would limit the amount of bioelements available. When there is a limit on the amount of bioelements available, then this inhibits population growth for many organisms. Carbon, nitrogen, sulfur, oxygen, phosphorus, and iron are elements that are needed and are able to be recharged because of biological, geological, and chemical mechanisms that are known as biochemical cycles. The biochemical cycles are the sulfur cycle, the carbon cycle, the nitrogen cycle, the phosphorus cycle, and other forms of cycling. These cycles all contribute to replenishing the essential elements to be used to promote population growth. Each cycle has different characteristics and a different process, but they have a few similarities between each cycle. The similarities between each group are each of the elements all came from nonliving things that were in either the atmosphere, lithosphere, or hydrosphere, each element goes to both abiotic and biotic environments, which means that they contribute to both nonliving parts of the environment and to living organisms in the environment. There also needs to be a balance of nutrients within the bioshpere when recycling; too much of nutrients may cause a build up. Cycles are all dependent on a system, which includes decomposers, consumers, and producers. Each has its role that it contributes to the cycle. Another criteria that each cyle shares is that certain microorganisms are able to convert inorganic compounds to another nutritional form, but all of the organisms play a part in the process of recycling. The Gaia theory was a concept that James Lovelock hypothesized about, which circles around the idea that the biosphere is comprised of different habitats and niches that are made to accommodate the living things that are there. Things are changed and adapted to by what living things are there. The earth and living things are able to interchangingly affect each other. The recycling process of bioelements are vital to the living and nonliving things as well as biotic and abiotic environments. Recycling is able to give the availability of the elements.

2. Good morning Professor and class, For puropose of this discussion I have chosen to discuss the management of wastewater and sewage. Before going into depth about this I will define what wastewater and sewage are.Wastewater is defined as water that has been used in a home or business and according to our textbook, “sewage is the used wastewater draining out of homes and industries that contains a wide variety of chemicals, debris, and microorganisms” (Talaro,2018). In various parts of the world the same water that serves as a source of drinking water also is used to dump wastes of all types. For centuries the threat of typhoid, cholera, and dysentry have all been linked to the unsanitary mixing of wastewater and sewage. The current practice is to treat some sewage to reduce the microbial count before being released, but there is still a large amountstill being dumped untreated due to the costs being to high. There are large amounts of solid wastes, dissolved organic matter and toxic chemicals that are in sewage that pose a healhrisk to humans; therefore it must be treated inorder to make it safe. There are three stages to the treatment. In the primary stage the large matter gets separted out, like the paper and plastic. The smaller particles stay and settle.In the secondary stage is when the remaining matter gets reduced and can remove some toxic substances. This is a stage of a “diverse community of natural bioremediators aerobically decomposes the remaining particles of wood, paper, fabrics, petroleum, and organic molecules inside a large digester tank”(Talaro,2018). The result of that process is a material called sludge. The third stage or tertiary stage completes the purification process of the water. Microbes and their activity is a huge part of the process of water treatment. In some places they use the sluge to make a secondary source of energy or fertilizer. Reference Talaro, K.
