Question

when organisms eat, the food is broken down and used to
i. supply energy for growth and repair.
ii. supply the building blocks for growth and repair.
iii. supply the energy for reproduction.
a. i and iii only
b. i only
c. ii only
d. i, ii, and iii

Explanation:

When organisms eat, the food is digested and used for multiple purposes. I: Food provides energy for growth and repair (e.g., cellular processes need energy). II: Food also supplies building blocks (like proteins, fats, carbs broken into smaller units) for growth/repair (e.g., amino acids for new cells). III: Reproduction also requires energy, which food provides. So I, II, and III are correct.

Answer:

D. I, II, and III
