Question

which energy-releasing process that occurs in both animals and plants uses oxygen and glucose as reactants and releases carbon dioxide, water, and heat as byproducts? combustion respiration homeostasis

Explanation:

Combustion is a non-biological reaction, not occurring in living plants/animals. Homeostasis is the maintenance of internal balance, not an energy-releasing process using oxygen and glucose. Cellular respiration (the process here called respiration) is the biological process in both animals and plants that uses oxygen and glucose to produce energy, releasing carbon dioxide, water, and heat as byproducts.

Answer:

respiration
