Water is continuously being recycled in a process called the water cycle. All living things on earth need water to survive. The water cycle has no starting point and no end point. Earth’s water is always in movement and always changing forms‚ it can go from a liquid to a solid to a gas and back to a liquid. The water cycle is how we track movement of water above‚ in and on the earth. The water cycle consists of three major processes‚ condensation‚ evaporation and precipitation. Condensation is 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

Several things occur in the Krebs cycle. It takes place in the mitochondrial matrix. The electron transport chain is located in the cristae of a mitochondria. The enzymes used during the Krebs cycle are found within the mitochondrial matrix excluding succinate dehydrogenase‚ which is bound to the inner mitochondrial membrane. Protein complexes located in the inner membrane perform the transfer and the gradual release of energy is used to pump protons into the intermembrane space of the mitochondria
