Explanation:

• "Living things use carbohydrates for energy": The text states "Carbohydrates are the primary source of energy for all living things", so this is true.
• "Carbohydrates are found in all foods": The text says "Carbohydrates are one of the three main types of biological macromolecules... found in the foods we eat", but it doesn't mean all foods. For example, pure fat or protein - rich foods without any added carbohydrates (like a very lean cut of meat with no seasonings that have carbs) may not have carbs. So this is false.
• "Some organisms use carbohydrates for structural support": The text mentions "Carbohydrates can also be used to form cell structures", so this is true.
• "Carbohydrates are made of carbon, hydrogen, and oxygen": The text clearly states "Carbohydrate molecules are made of carbon, hydrogen, and oxygen", so this is true.

Answer:

Living things use carbohydrates for energy.
Some organisms use carbohydrates for structural support.
Carbohydrates are made of carbon, hydrogen, and oxygen.
