In an energy pyramid, what is the role of a producer?

• A. To produce oxygen in the atmosphere.
• B. To convert sunlight into chemical energy stored in organic matter.
• C. It decomposes dead material.
• D. It pollinates flowers.

Answer: (B)

In an energy pyramid, the role of a producer is to capture sunlight and convert it into chemical energy stored in organic matter through photosynthesis. This stored energy becomes the base fuel for all other organisms higher up the pyramid, providing the energy that herbivores and, in turn, predators rely on. While producers do release oxygen as a byproduct of photosynthesis, the essential function in the pyramid is converting light into stored chemical energy. The other roles described—decomposing dead material or pollinating flowers—are handled by other organisms and don’t define the producer’s place in the energy pyramid.
