Quizplus · Accepted Answer

Bacteria that make their own carbohydrates by obtaining energy from chemical compounds are known as chemoautotrophs. They do not rely on sunlight as a source of energy, and instead use chemicals such as sulfur, iron, or ammonia to produce their own food. Cyanobacteria, phytoplankton, and protists are all examples of organisms that utilize photosynthesis to obtain energy. Heterotrophs obtain their energy by consuming other organisms or organic matter.
