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 types of complex organic compounds can certain organisms produce?

• Enzymes and hormones

• Vitamins and minerals

• Proteins and carbohydrates

• Lipids and nucleic acids

What is often required to provide energy for the production of organic compounds?

• Water

• Heat

• Oxygen

• Light

Which organisms are considered critical producers in ecosystems?

• Herbivores

• Autotrophs

• Decomposers

• Carnivores

What role do autotrophs play in ecosystems?

• They provide shelter for animals.

• They fix chemical energy and raw materials.

• They consume other organisms.

• They decompose organic matter.

Why are autotrophs important for organisms higher up in the food chain?

• They produce oxygen.

• They provide necessary energy and materials.

• They control the population of herbivores.

• They recycle nutrients.
