Cycling of Matter

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

• Photosynthesis converts carbon dioxide to oxygen

• Photosynthesis captures oxygen and returns it to the atmosphere

• Photosynthesis converts oxygen to carbon dioxide

• Photosynthesis captures carbon and returns it to the atmosphere

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

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

• They break down dead organisms and return nutrients to the soil

• They consume glucose and use it for their own energy needs

• They return carbon to the atmosphere through respiration

• They capture energy from the sun and store it as chemical energy in glucose

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
