Question

what is the process called where oxygen and glucose is created by plants?
a food web
respiration
photosynthesis
breathing

Explanation:

Photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to produce glucose (a sugar) and oxygen. A food web is a complex network of feeding relationships in an ecosystem. Respiration is the process by which organisms (including plants) break down glucose to release energy (plants also respire, but it's different from the process of creating glucose and oxygen). Breathing is a part of the respiratory process in animals (taking in oxygen and expelling carbon dioxide).

Answer:

C. Photosynthesis
