Question

question 15 of 25
which two processes involved in a biogeochemical cycle cause atoms of elements to be recombined into new molecular products?
a. photosynthesis
b. condensation
c. combustion
d. precipitation

Explanation:

Photosynthesis uses light - energy to recombine carbon dioxide and water into glucose and oxygen. Combustion is a chemical reaction that recombines elements in a fuel with oxygen to form new products like carbon dioxide and water. Condensation and precipitation are mainly physical processes and do not involve recombination of atoms into new molecular products in the context of biogeochemical cycles.

Answer:

A. Photosynthesis, C. Combustion
