Future Food- Lesson 2 Quiz

Cows use cellular respiration to turn their food into energy. A cow eats 4.5 kg of grass and releases 2,500 L of carbon dioxide a day. As the cow gets older it eats 9 kg of grass a day. Approximately how much carbon dioxide do you think the cow will release during cellular respiration when it eats 9 kg of grass a day?

• The cow will release about 5,000 L of carbon dioxide a day because matter is conserved during cellular respiration. If the cow released 2,500 L of carbon dioxide when it ate 4.5 kg of food, it makes sense that the amount of gas released would double when eating double the food..
• The cow will release about 1200 L of carbon dioxide a day because matter is conserved during cellular respiration. If the cow released 2,500 L of carbon dioxide when it ate 4.5 kg of food, it makes sense that the amount of gas released would not change when it eats 9kg of food.
