Have you ever wondered why your stomach grumbles after running around at recess, or why a cheetah takes a long nap after a fast hunt?
Just like a toy car stops when its battery runs out, every animal needs fuel to stay alive and active.
Where do animals get this fuel if they cannot plug into a wall?
Where Animals Get Their Fuel
Plants can make their own food using sunlight, but animals cannot make their own food.
Instead, animals must consume plants, other animals, or both to get nutrients—the usable parts of food that provide energy and raw building materials.
📊A side-by-side visual comparison showing how plants and animals get food. Left side: A green plant in soil with sunbeams shining on it, labeled 'Plants: Make their own food using sunlight'. Right side: A rabbit eating a carrot and a fox eating food, labeled 'Animals: Must eat other living things'. Clean cards with soft gray borders, rounded corners, soft green and orange accents, clear icons.
Once an animal eats its food, what does its body actually use all that energy for?
The 4 Jobs of Food
Every animal uses the food it consumes for four vital jobs: movement, growth, repair, and body warmth.
📊A 2x2 grid showing the 4 main reasons animals need food: 1. Movement (running cheetah icon with motion lines), 2. Growth (tiny chick next to a full-grown hen), 3. Repair (bandaged paw showing new skin healing), 4. Body Warmth (thermometer showing cozy 98.6°F next to an arctic penguin). Each box has a bold title, a short 1-line description, and a distinct pastel color background (blue, green, orange, purple).
Let's zoom into the first job: why do your muscles need breakfast before gym class?
