Photosynthesis uses energy from the sun to split water into oxygen and hydrogen. The oxygen passes into the atmosphere and the hydrogen joins with carbon dioxide to produce biomass. When living things need energy they take in oxygen for respiration. The oxygen returns to the atmosphere in the form of carbon dioxide.
Sewer Main Costs. 1  If youâve noticed symptoms of a bad sewer main, itâs probably worth paying somebody $250 to $500 to use a diagnostic camera to check it out because main line sewer repair is expensive. 2  If the line is clogged by tree roots or other blockage, you can use a sewer snake to try and clear them out.
