Question

carbon is eventually returned to the atmosphere through which of the following? choose one option a cellular respiration b photosynthesis c dna replication d cell division

Explanation:

Cellular respiration breaks down organic molecules like glucose and releases carbon - dioxide into the atmosphere. Photosynthesis takes in carbon - dioxide from the atmosphere and uses it to make organic compounds. DNA replication and cell division are processes related to the duplication of genetic material and cell growth respectively, and do not directly return carbon to the atmosphere.

Answer:

A. Cellular respiration
