Where Does Energy Go as It Moves Up a Food Chain?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Where does energy go as it moves up a food chain?

The Big Idea

A rabbit eats grass, and a fox eats the rabbit. But energy gets smaller at every step. Let's find out where it goes!

Grass to Rabbit

Step one: grass to rabbit. When a rabbit eats grass, it uses most of the energy for moving, staying warm, and living. Only about a tenth is stored in its body.

Rabbit to Fox

Step two: rabbit to fox. If a fox eats the rabbit, only about a tenth of that is passed on. The rest escapes as heat.

Less to Share

Step three: less to share. So each step up the chain has less energy to share. That makes an energy pyramid, wide at the bottom and narrow at the top.

A Closer Look

Let's take a closer look! Grass has the most energy. The rabbit keeps a tenth. The fox gets a tenth of that. The rest becomes heat.

Quick Facts

Quick facts! This is called the ten percent rule. Animals use most of their energy to move and stay warm. Remember, the rest escapes as heat. That is why the energy pyramid gets narrower toward the top.

Think Like a Scientist

Now, think like a scientist! Draw an energy pyramid. Put grass at the bottom, a rabbit in the middle, and a fox on top. Make each level smaller than the one below. Label how much energy is left at each level. Tell a grown-up what you discover!

Outro

Energy shrinks as it moves up a food chain, because most of it is used or lost as heat at each step. Science is amazing! Keep wondering and keep exploring! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
