Answer:
Photosynthesis
Step-by-step explanation:
Photosynthesis is a process unique to autotrophic organisms like plants. They use this photosynthetic process to convert carbon- containing molecules to useful products like sugar e.g glucose.
Photosynthesis is the process whereby plants combine carbondioxide (CO2) and water (H2O) to form food in form of sugar (glucose) in the presence of sunlight. Plants due to their unique ability to capture light energy from the sun are able to perform this process.
