Final answer:
The term that BEST describes organisms using light to make organic molecules from inorganic ones is photosynthesis, carried out by photoautotrophs.
Step-by-step explanation:
The term that BEST describes organisms that specifically utilize light energy to make organic molecules from inorganic molecules is photosynthesis. These organisms, such as plants, algae, and cyanobacteria, are known as photoautotrophs. They can capture light energy and convert carbon dioxide and water into glucose and oxygen through photosynthesis, providing energy for themselves and other organisms.
Autotrophs, such as plants, algae, and some bacteria, are able to produce their own food through photosynthesis by using sunlight, carbon dioxide, and water to produce glucose and oxygen. Heterotrophs, on the other hand, rely on the sugars produced by photosynthetic organisms for their energy needs.
