2
Sources of Energy - Photosynthesis Nearly all living things obtain energy either directly or indirectly from the energy of sunlight captured during photosynthesis.
3
The Two Stages of Photosynthesis
During photosynthesis, plants and some other organisms use energy from the sun to convert carbon dioxide and water into oxygen and sugars.

15
Two Stages of Respiration
During respiration, cells break down simple food molecules such as sugar and release the energy they contain.

Photosynthesis and Respiration
You can think of photosynthesis and respiration as opposite processes.
