Question: Why don’t plants live in completely dark places?

Sample Explanation 2:

Plants don’t live in completely dark places because plants need light. The reason plants need light is because light allows them to make the food they need to grow and make seeds. A plant’s leaves get energy from sunlight. and that energy allows the plants to make their own food from air and water. Plants use this food to release energy for growth.
