Question

what is the process by which a producer uses light energy to make sugars from carbon dioxide and water?
respiration
photosynthesis
homeostasis
development
reproduction

Explanation:

Photosynthesis is the process where producers (like plants) convert light energy into chemical energy (sugars) using carbon dioxide and water. Respiration is the opposite (breaking down sugars for energy). Homeostasis is maintaining internal balance. Development is growth - related. Reproduction is creating offspring.

Answer:

photosynthesis
