I will start by describing the carbon cycle and how elements of my lifestyle impact the cycle. Photosynthesis converts the Carbon dioxide gas that exists in the atmosphere and in dissolved water to organic carbon. Organic carbon is brought back into carbon dioxide gas by a process called respiration. There are sources of organic carbon underground in the form of fossil fuels‚ human emissions and volcanic activity brings the stored carbon back into the cycle. As a human being who feed‚ move‚ breath

rock cycle operates. How do rocks metamorphose at destructive plate boundary? Rock cycle is a cycle that describes how rocks are transformed. Igneous rock can change into sedimentary rock or metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock. Besides‚ metamorphism at the destructive plate boundaries creates different characteristics of rocks. Operation of the rock cycle The Rock Cycle

A nutrient cycle (or ecological recycling) is the movement and exchange of organic and inorganic matter back into the production of living matter. The process is regulated by food web pathways that decompose matter into mineral nutrients. Nutrient cycles occur within ecosystems. Ecosystems are interconnected systems where matter and energy flows and is exchanged as organisms feed‚ digest‚ and migrate about. Minerals and nutrients accumulate in varied densities and uneven configurations across the

------------------------------------------------- The Processes of the nitrogen cycle Nitrogen fixation Atmospheric nitrogen must be processed‚ or "fixed" (see page on nitrogen fixation)‚ in order to be used by plants. Some fixation occurs in lightning strikes‚ but most fixation is done by free-living or symbiotic bacteria. These bacteria have the nitrogenase enzyme that combines gaseous nitrogen with hydrogen to produce ammonia‚ which is then further converted by the bacteria to make their own organic

Managing the Guest Cycle The guest cycle describes the activities that each guest passes by from the moment he/she calls to communicate a reservation inquiry until he/she departs from the hotel. The hotel guest stay cycle can be divided into four main stages. Within these four stages there are important task related to guest services and guest accounting. The Four Stages of Guest Cycle: 1. Pre-Arrival 2. Arrival 3. Occupancy 4. Departure Below is a description of the activities

Oxygen Cycle Required for Life All living things use oxygen or depend on organisms that use oxygen in some way. All Animals and Other Consumers Use Oxygen We use oxygen to break down simple sugar and release energy. This can be done through respiration or fermentation. Animals mainly use respiration. Respiration The process that breaks apart simple food molecules to release energy. It occurs inside cells. What YOU do with the oxygen

A cycle is defined as any complete round or series of occurrences that repeats or is repeated in the same order and at the same intervals. The natural existence of cycles is highly important without cycles resources would run out and organisms would die. The amount of carbon nitrogen and oxygen on the earth is fixed‚ they can exists in different forms but no more may be added. So that these don’t run out they are cycles so they may be reused. Photosynthesis and respiration are the reverse of each
