What is Energy?
Every living thing needs fuel to grow, move, and survive.
The ultimate engine behind all life on Earth is the Sun!
💡 Fun Fact: Without sunlight, ecosystems couldn't exist! Plants are the vital link that traps solar energy.

The Consumer
cannot make food. They must EAT!
🐛 PLANTS
Herbivore
Eats only producers (plants, leaves, seeds).
Example: Caterpillar
🐍 MEAT
Carnivore
Eats only other animals (meat eaters).
Examples: Snake, Eagle
🐭 BOTH
Omnivore
Eats both plants and animals for energy.
Example: Mouse
We label consumers based on WHAT they eat! Next: Explorer Video! 🎥

Slide 6 of 12
Where Does the Arrow Point?
THE GOLDEN RULE:
The arrow always points to the Predator (the eater)!
It represents the flow of energy. The animal pointing to is getting the energy in their stomach.

Building Different Paths (Q5 - Q7)
Different organisms choose different menus in the same ecosystem!
5 Chain A:
Grass 🌱 Mouse 🐭 Fox 🦊
6 Chain B:
Grass 🌱 Mouse 🐭 Eagle 🦅
7 Chain C:
Grass 🌱 Grasshopper 🦗 Snake 🐍 Fox 🦊
Each path shows a separate flow of solar power! Next: What is a Food Web? ➡️

What is a
Food Web?
In an ecosystem, food chains don't exist alone! They overlap to create a massive, beautiful Web.
"A food web is made of multiple food chains tangled together."
