What does producers depend on for food

Producers make food for the rest of the ecosystem through the process of photosynthesis, where the energy of the sun is used to convert carbon dioxide and water into glucose.  We say that producers take matter from the air, water, and soil to make their own food.

Scientists use the name matter for the stuff that plants combine to make food. We say that producers take matter from the air, water, and soil to make their own food. Producers use energy from the sun to make food from matter. Producers do more than produce food.

I think it shows the conflict of the story, im not sure.
