Organisms may derive energy from
A) sunlight AND temperature gradients.
B) sunlight AND metabolizing chemical compounds.
C) metabolizing chemical compounds AND temperature gradients.
D) temperature gradients AND pH gradients.
E) sunlight AND pH gradients.

Question

Quizplus · Accepted Answer

Organisms can derive energy from sunlight through the process of photosynthesis and also by metabolizing chemical compounds through cellular respiration. Sunlight provides energy in the form of photons, while metabolizing chemical compounds provides energy by breaking down organic molecules and releasing stored energy. Temperature gradients and pH gradients can affect metabolic processes, but they do not provide energy sources for organisms.
