Verified step by step guidance1
Understand the prefix 'photo-': In microbiology, the prefix 'photo-' is derived from the Greek word 'phōs,' meaning light. It indicates that the organism uses light as a source of energy.
Identify the types of energy sources: Organisms can utilize different sources for energy, including light, chemicals, organics, and inorganics.
Differentiate between phototrophs and chemotrophs: Phototrophs use light as their energy source, while chemotrophs rely on chemical compounds.
Consider examples of phototrophic organisms: Many plants, algae, and certain bacteria are phototrophs, using light to drive photosynthesis.
Conclude the correct answer: Based on the prefix 'photo-', the organism uses light for energy purposes, distinguishing it from organisms that use chemicals, organics, or inorganics.
