Question

Chemosynthesis relies on chemical energy in the environment. The fact that no large organisms are known to undergo chemosynthesis suggests (1 point)
• chemical energy in the environment is equal to light energy.
• chemical energy can never directly support large organisms.
• chemical energy in the environment is weaker than light energy.
• chemical energy is toxic to large organisms.

Answer 1

• chemical energy in the environment is weaker than light energy.
