What happens to the carbon stored in glucose when animals eat plants?

• It is passed along the food chain
• It is released back into the atmosphere
• It is converted into oxygen
• It is absorbed by the soil

What is the role of herbivores in the cycling of matter?

• They return carbon to the atmosphere through respiration
• They capture energy from the sun and store it as chemical energy in glucose
• They eat plants and return nutrients to the soil
• They consume glucose and use it for their own energy needs
