Why is this the answer?

The answer is fire because this is a super clever riddle that makes you think about how fire works, almost like a living thing. It is a wonderful word puzzle that uses everyday actions, like eating and drinking, to describe a natural chemical reaction. For a fire to be strong and keep burning, it needs something to "eat." What is the food that fire needs? It is things like wood, paper, dry leaves, and other kinds of fuel. When a firefighter or a camper puts a log on a small flame, they are "feeding" it, and when you feed it, the fire grows bigger, hotter, and brighter. It stays "alive," or burning strongly. So, the riddle says, "Feed me and I live," and that is exactly what happens when you give fuel to a fire. The fuel is its food, and the fire must have that food to keep its special chemical reaction going. Now let's think about the second, trickier part of the riddle: "Give me drink and I die." What is the one thing we always use when we want to stop a fire from burning? We use water! When you pour water onto a fire, the water does two important jobs. First, it cools the fire down very quickly, taking away its heat. Second, the water creates steam, which helps to keep the air, or the oxygen, away from the fuel. Fire needs heat, fuel, and oxygen to live, and the water takes away two of those things. When the heat and air are gone, the fire cannot keep burning, and it goes out, or "dies." So, the water is the "drink" that makes the fire die. This riddle is an example of personification, which is when we describe an object, like fire, as if it were a person with human actions. It is a fun way to remind us of the important science of fire safety and the amazing power of a tiny flame.
