Autótrofo

The video explains how complex organic compounds like proteins and carbohydrates are produced, requiring energy often from light. It highlights the role of autotrophs, such as algae and plants, as essential producers in ecosystems. These organisms fix chemical energy and provide raw materials necessary for the survival of higher organisms in the food chain.

What are the raw materials that autotrophs fix to produce energy?

Explain how autotrophs contribute to the food chain.
