Question

During a class discussion, a classmate states that animals consume food and oxygen to support their growth. You know that the digestive and respiratory systems work together to breakdown food and absorb oxygen, which are then used by cells.

Which statement provides evidence to support how animals use matter from food for growth?

Animals transform energy from the sun into chemical energy that can be used for growth and repair.

Answer 1

Animals use ingested food and oxygen for metabolic reactions in cells, and form new molecules for growth.

Explanation: Food provides the matter (carbon, hydrogen, etc.) used to build new cell structures and tissues, and oxygen is used in cellular respiration to release energy needed for those biosynthetic reactions. Exhaled CO2 is a waste product, not material reused to form new body parts.
