Autotroph

The video explains how autotrophs like algae and plants produce complex organic compounds such as proteins and carbohydrates, which are essential for life. This process requires energy, often derived from light. Autotrophs play a crucial role in ecosystems by capturing chemical energy and raw materials needed by organisms higher up the food chain.

What types of complex organic compounds can certain organisms produce?

• Vitamins and minerals

• Water and oxygen

• Lipids and nucleic acids

• Proteins and carbohydrates

What is often required for the production of complex organic compounds?

• Water

• Light

• Carbon dioxide

• Oxygen

Which organisms are considered key producers in ecosystems?

• Herbivores

• Carnivores

• Autotrophs

• Decomposers

What do autotrophs provide for organisms higher up the food chain?

• Shelter and protection

• Chemical energy and raw materials

• Water and air

• Predation and competition

Which of the following is an example of an autotroph?

• Fungi

• Algae

• Insects

• Mammals
