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 weaker than light energy.

chemical energy can never directly support large organisms.

chemical energy in the environment is equal to light energy.

chemical energy is toxic to large organisms.

Answer 1

chemical energy in the environment is weaker than light energy.

Reason: lower energy flux from chemical sources limits the amount of biomass and size they can support; it doesn't prove chemosynthesis can never support large organisms or that chemicals are toxic or equal in energy to light.
