Which process is responsible for breaking down dead organic matter in an ecosystem?

• Photosynthesis

• Chemosynthesis

• Decomposition

• Aerobic respiration

What is the main difference between photosynthesis and chemosynthesis?

• Photosynthesis uses sunlight, while chemosynthesis uses chemical energy

• Photosynthesis occurs in animals, while chemosynthesis occurs in plants

• Photosynthesis produces oxygen, while chemosynthesis produces carbon dioxide

• Photosynthesis requires oxygen, while chemosynthesis does not
