Cellular Respiration and Photosynthesis Concepts

Miss Fati's lesson explores how carbon dioxide enters ecosystems, focusing on cellular respiration. The lesson uses a digital model to simulate the process, showing how producers, consumers, and decomposers contribute to carbon dioxide production. Cellular respiration is compared to photosynthesis, highlighting their opposite reactions. The role of dead matter in carbon dioxide release is also examined, emphasizing the importance of these processes in energy storage and ecosystem balance.

What materials are recommended for the lesson on carbon dioxide in ecosystems?

• A piece of paper and a pen

• A calculator and a ruler

• A laptop and headphones

• A textbook and a highlighter

What process do decomposers use to produce carbon dioxide?

• Fermentation

• Cellular respiration

• Photosynthesis

• Combustion

In the digital model, what molecules are released during cellular respiration?

• Oxygen and glucose

• Hydrogen and oxygen

• Carbon dioxide and water

• Nitrogen and methane

How do cellular respiration and photosynthesis relate to each other?

• They are identical processes

• They are unrelated processes

• They are opposite reactions

• They occur in the same organelle

What is the role of energy in photosynthesis?

• Energy is released from glucose

• Energy is absorbed from sunlight

• Energy is stored in water

• Energy is converted into oxygen

What happens to dead matter when it is burned?

• It releases oxygen

• It releases carbon dioxide

• It absorbs water

• It produces glucose

Which organisms in the ecosystem perform cellular respiration?

• Only consumers

• Only producers

• All living organisms

• Only decomposers

What are the reactants of cellular respiration?

• Nitrogen and hydrogen

• Methane and oxygen

• Glucose and oxygen

• Carbon dioxide and water

What is the main purpose of cellular respiration?

• To release energy

• To produce glucose

• To absorb sunlight

• To create oxygen

What is the relationship between the products of photosynthesis and the reactants of cellular respiration?

• They are the same

• They are unrelated

• They are opposite

• They are identical
