Which statement about producers is true?

• A. Producers convert sunlight energy into chemical energy through photosynthesis
• B. Decomposers convert sunlight energy into chemical energy
• C. Consumers convert sunlight energy into chemical energy
• D. Detritivores store energy in chemical bonds only after consumption

Answer: (A)

The idea being tested is how energy enters an ecosystem through producers. Producers, such as plants, algae, and some bacteria, capture sunlight and use it to make chemical energy stored in sugars through a process called photosynthesis. This stored energy in chemical bonds can then be transferred to other organisms when they eat the producers, starting the flow of energy through the food web. That’s why the statement about producers is the best: they are the ones that directly convert light into chemical energy. The other roles don’t do this: decomposers break down dead material rather than capturing sunlight, consumers obtain energy by eating other organisms, and detritivores feed on detritus rather than directly storing energy from sunlight.
