Cave ecosystems are characterized by extremely low light levels. What role does photosynthesis play in a cave ecosystem?
===
Photosynthesis is essential because it provides the original energy source for all food chains in this ecosystem.
Photosynthesis is essential only for those organisms that must travel outside of this ecosystem to acquire food.
Photosynthesis is optional because some organisms use sources inside and outside of this ecosystem for food.
Photosynthesis is not needed since organisms have adapted to live in the dark where photosynthesis cannot take place.
