Primary producers are the basis of any food chain. Sunlight powers photosynthesis which results in the production of chemical en
ergy, glucose. Some organisms are known to survive in dark habits in which sunlight cannot penetrate. What process is responsible for how these organisms obtain energy? A) chemosynthesis B) photosynthesis C) Spermatogenesis D) Cellular respiration
Organisms, such as bacteria and other living organisms, use chemosynthesis when there is an absence of light. They use inorganic chemicals to produce energy through reactions.
