Which statement i true for photosynthesis ? a. producers use it b. consumers use it c. scavengers use it d. decomposers use it

Answer is: A. Producers use it.

Plants convert solar energy into the chemical energy of sugars (food).

Solar energy is stored in chemical bonds of sugars (glucose for example).  

The overall balanced photosynthesis reaction:  

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.

In carbon dioxide, carbon has oxidation number +4 and in photosynthesis carbon gain electrons (solar energy), so his oxidation number is lowered (reduced). Light energy is transformed into chemical energy, that is stored in carbohydrate molecules (glucose), which are synthesized from carbon dioxide and water.  

they are made of gases.

they have a spherical shape.

they make energy through fusion.
