A Correct answer
Explanation

Cellular respiration is the metabolic process where cells break down glucose in the presence of oxygen to produce ATP, releasing carbon dioxide and water as waste products. This occurs through glycolysis, the Krebs cycle, and oxidative phosphorylation. Transpiration is water loss through leaves, decomposition is breakdown by decomposers, and fossilization is preservation of remains.
