Answer: Need sugar for energy
Explanation: Plants exhibit an autotrophic type of nutrition that is, plants manufacture their own food. They have chlorophyll a green pigment located in the leaves to trap sunlight and convert carbon dioxide and water to glucose and oxygen in a process called photosynthesis. The glucose which is a simple sugar is then transported to other plant tissues where they are needed as source of energy for growth and other metabolic functions.
Animals exhibit a heterotrophic type of nutrition that is, animals cannot manufacture their own food rather they depend on plants and/or other animals for food. Animals use sugars derived from food they eat to obtain energy for all bodily functions.
