Revising a Key Concept About Food Molecules
You have been investigating where plants get their food molecules. We’ve learned they make them by using water, energy from sunlight, and carbon dioxide from the air.
Back in lesson ER 1.5, we gathered evidence about animals needing energy for movement and growth.
Key Point: Animals use some food molecules to release energy for movement and growth.
You're going to use the sim to answer 2 questions:
1) What do plants use energy for?
2) Where does energy in the ecosystem come from?

What evidence did you find that shows plants use or do not use some food molecules for energy?

In the simulation, it shows ________________________________________________________________________
Gathering Evidence About Energy
We know that the food molecules in an ecosystem come from plants. But - Where does energy in an ecosystem come from? We’ll investigate TWO possible claims and look for evidence in the Simulation.
