This kit allows students to collect samples from the world around them and grow the … Microenvironments are small spaces or locations within the Earth's ecosystem where some environmental factors differs from another that is nearby. Microbes are everywhere in the biosphere, and their presence invariably affects the environment that they are growing in. Bacteria play an important role in the environment: Decomposition of Dead/Complex Organic Matter: ... Bacteria, and other micro-organisms are essentially important in the cycling of nutrients and energy, particularly in the breakdown of dead organic matter to make the resources locked up in things like dead trees available again to other living organisms. They pose less threat to the … The human host and its microbial flora constitute a complex ecosystem whose equilibrium serves as a … Free Preview. Different species of microbes live at different places in and on human body and these are adapted to the conditions in these places [2]. In household Food processing . Monitoring and characterizing bioremediationRemediation of contaminated soil and groundwater is often a costly and complicated affair. CONCLUSION Based on the benefits of the use of microbes in controlling pests, the process helps in reducing environmental and public safety hazards of chemicals. Thus, microorganisms can be used to degrade the harmful and smelly substances and thereby cleans up the environment. The environment, in this case, means the soil, water, air and sediments covering the planet and can also include the animals and plants that inhabit these areas. x. Size.
