In what way do aerobic conditions differ from anaerobic conditions in terms of matter cycling?

• Aerobic conditions involve the cycling of carbon dioxide, while anaerobic conditions do not

• Aerobic conditions occur only in the presence of sunlight

• Anaerobic conditions require more energy input

• Anaerobic conditions involve the cycling of nitrogen, while aerobic conditions do not

What might happen to an ecosystem if a key species is removed?

• The ecosystem will remain unchanged
