You may have noticed that there are numbers in front of the compounds in the chemical equation for photosynthesis. This is because this is a "balanced" chemical equation. In terms of conservation of matter, why must the chemical equation for photosynthesis be balanced?

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.
