What are organisms called that perform photosynthesis to obtain energy?

• A. Heterotrophs
• B. Decomposers
• C. Photoautotrophs
• D. Consumers

Answer: (C)

Organisms that perform photosynthesis to obtain energy are classified as photoautotrophs. This term denotes those organisms that use light energy to convert carbon dioxide and water into glucose and oxygen through the process of photosynthesis. The ability to harness sunlight allows photoautotrophs, such as many plants, algae, and certain bacteria, to generate their own organic compounds, making them foundational to ecosystems as primary producers. In contrast, heterotrophs, decomposers, and consumers rely on other organisms for their energy and nutrient needs. Heterotrophs obtain energy by consuming organic material produced by other organisms. Decomposers, such as fungi and bacteria, break down dead organic matter, returning nutrients to the ecosystem. Consumers are organisms that feed on other living things for energy, whether plants or other animals. These groups do not perform photosynthesis and instead depend on the energy created by photoautotrophs.
