Look at the key. Which group changed over time?

• Decomposers
• Producers
• Consumers

What does cellular respiration need to occur? (check all that apply)

• oxygen
• glucose
• energy
• carbon
• water

p.38 Do producers give off or take in carbon dioxide?

• They only give off
• They only take in
• They do both take in and give off

Which are decomposers? (check all that apply)

• fungi
• trees

• mushrooms
• soil bacteria
• worms

What is cellular respiration?

• A way to release carbon in organisms.
• The chemical reaction between oxygen and glucose that releases energy into cells

• When decomposers are able to release carbon found in dead matter, making it available to the ecosystem.
• In cell parts called the mitochondria, glucose (an energy storage molecule) plus oxygen combine to make carbon dioxide plus water, releasing energy.

Where does cellular respiration take place?

• In the chloroplast
• In the nucleus
• In the mitochondria
• In the DNA
