In an introduction to photosynthesis, which type of organisms perform photosynthesis as their primary method of producing organic molecules?

• A. Decomposers
• B. Autotrophs
• C. Heterotrophs
• D. Parasites

Answer: (B)

Verified step by step guidance

1. Understand the key terms: Photosynthesis is the process by which certain organisms convert light energy into chemical energy, producing organic molecules like glucose.
2. Identify the types of organisms listed: Decomposers break down dead material, heterotrophs consume other organisms for energy, parasites live off hosts, and autotrophs produce their own organic molecules.
3. Recall that autotrophs are organisms capable of photosynthesis, meaning they use light energy to synthesize organic compounds from inorganic substances like carbon dioxide and water.
4. Recognize that the question asks which organisms perform photosynthesis as their primary method of producing organic molecules, which aligns with the definition of autotrophs.
5. Conclude that autotrophs are the correct answer because they are the primary producers in ecosystems, using photosynthesis to create organic molecules essential for life.
