Three students were talking about this question:
Question: Do living things have to gain energy to stay alive?
Billy Bob: "Living things don't need to gain energy to stay alive. Only robots and machines need energy to keep working."
Susieeeeeeeee: "I think all living things need to gain energy so they can live and grow."
Jimothy: "I think plants need to gain energy, because they need sunlight, but animals don't."
