1 Navy pilots move a lot, both during and after training. During your 2 to 2.5 years of flight school, you can expect to move 3 or 4 times. While you will be home during school, you will work odd and often inconsistent hours.  Your work obligations are dependent on your country's needs.
], respiration [respiration: Chemical change that takes place inside living cells, which uses glucose and oxygen to produce the energy organisms need to live. Carbon dioxide is a by-product of respiration ] and combustioncombustion: Combustion is the process of burning by fire.. Green plants remove carbon dioxide from the atmosphere by photosynthesis. Living organisms - including all plants and animals - release energy from their food using respiration. Respiration and combustion - burning - both release carbon dioxide into the atmosphere.
Carbon fixation or Ñarbon assimilation refers to the conversion process of inorganic carbon (carbon dioxide) to organic compounds by living organisms.The most prominent example is photosynthesis, although chemosynthesis is another form of carbon fixation that can take place in the absence of sunlight.n photosynthesis, energy from sunlight drives the carbon fixation pathway. Oxygenic photosynthesis is used by the primary producers âplants, algae, and cyanobacteria. They contain the pigment chlorophyll, and use the Calvin cycle to fix carbon autotrophically.
