Energy from the sun heat and chemicals
Respiration is how animal cells get their energy to preform their necessary functions. Plant cells don't use respiration, because they use photosynthesis. Photosynthesis turns light into energy.
Tid-bit of info:
Cellular Respiration Formula:
Sugar + Oxygen = Carbon Dioxide + Water <span>+ ATP </span>
C₆H₁₂O₆ + O₂ = CO₂ + H₂O <span>+ ATP </span>
Photosynthesis Formula:
Sunlight + Water + Carbon Dioxide = Oxygen + Sugar
Sunlight + H₂O + CO₂ = O₂ + C₆H₁₂O₆
