What role do producers play in an ecosystem?

• A. They store energy in the air.
• B. They convert sunlight into chemical energy through photosynthesis.
• C. They break down dead matter.
• D. They eat other animals.

Answer: (B)

Producers capture light energy from the sun and convert it into chemical energy stored in sugars through photosynthesis. This stored energy forms the base of the ecosystem's food web, providing the source that all other organisms—herbivores and then carnivores—rely on for energy. Energy flows from producers to consumers in a food chain, so producers are essential for starting that flow. The other ideas don’t fit because energy isn’t stored in the air, decomposers break down dead matter, and eating other animals describes consumers, not producers.
