Describe how living things are involved in the constant cycling of carbon

All living organisms are involved in the carbon cycle because we either do cellular respiration and plants do photosynthesis. When humans breathe we take in oxygen and breathe out carbon dioxide. Plants then take in the carbon dioxide we breathe out and turn it into oxygen which we then breath in. The cycle continues constantly like this.  

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
