10. Which statement best explains why cellular respiration in plants and other organisms is dependent on photosynthesis?

Cellular respiration depends on two chemical reactants; glucose and oxygen.  Glucose and oxygen are made available to plants and animals for cellular respiration thanks to photosynthesis.  Photosynthesis is the chemical reaction that uses solar energy to convert water and carbon dioxide into glucose and oxygen.  Without photosynthesis, the available glucose and oxygen on the planet would quickly deplete to the point that life could not be sustained on Earth. So the answer would be B :).

Explanation: Hope this helps and good luck :)!

Since photosynthesis is the process whereby plant manufacture its own food using a sunlight, so respiration can happen because plant is alive
