Explanation: Organisms need two things to maintain themselves, grow and reproduce. These are: 1) energy and 2) nutrients. Step by Step Solution: Step 1. Energy is the capacity to do work and is required to carry out various life processes including movement, growth, cell division, and reproduction. Energy is obtained by the breakdown of nutrients. Step 2. Nutrients include carbohydrates, lipids, proteins, vitamins, and minerals. These molecules are broken down during digestion, and the body uses them for various functions such as building new tissue, repairing damaged tissue, and providing energy. Step 3. Therefore, the two things that organisms require to maintain themselves, grow, and reproduce are energy and nutrients. Final Answer: Organisms require energy and nutrients to maintain themselves, grow, and reproduce.
