False
In a food chain, When a rabbit eats hay, the hay is the rabbits source of _____.
energy
water
sunlight
carbon dioxide
Plants take in what gas and use it for making food?
carbon dioxide
oxygen
hydrogen
nitrogen
What part of a plant is used to collect energy from sunlight?

True
False
The figure shows an ecosystem with different plants and animals. What statement can you make about the flow of energy in this ecosystem?
On a rainy day, no energy will flow in this ecosystem.
Grass can use and store energy from the sun, which eventually flows to all of the other life forms.
Eagles get their energy from the sun.
If eagles are removed from the ecosystem, plants will die.
How can you tell if an animal is growing in the simulation?
Matter cubes are being added to the animal's body from the food matter it takes in.
Matter cubes are not being added to the animal's body.
Matter cubes are escaping the organism and falling to the ground.
When animals eat food, they take in the body molecules of plants or other animals. Why is this done?
They use them to build and grow their bodies and to release energy.
They use them to build more food.
They are not used for anything.
Molecules disappear once inside of the plant or animal.
According to the Healthy Ecosystem Model, what happens to the grass molecules once they are eaten by the zebra?
The grass molecules disappear.
The grass molecules are transferred into the cheetah.
The grass molecules turn into zebra body molecules so the zebra can move and grow.
There is no change to the grass molecules.
According to the Healthy Ecosystem Model, what happens to the zebra molecules once they are eaten by the cheetah?
The zebra molecules turn into light molecules.
The zebra molecules are released into the grass.
The zebra molecules turn into cheetah body molecules, or they are released as energy so the cheetah can move and grow.
There is no change to the zebra molecules.
After the cheetah eats a zebra what happens to the zebra molecules inside the cheetah (use your ideas from the previous unit on chemical reactions) ?
The molecules disappear.
There is not a chemical reaction taking place.
The zebra becomes grass molecules.
There is a chemical reaction taking place in which the the zebra body molecules are turning into cheetah body molecules.
Based on what happened in the Sim, what happens to the food molecules in an animal's body? Select 3 correct answers.
Some are used to make body molecules
Some are released as energy that helps the animal move
Some are released as waste
Some molecules are stored in the animal's body then disappear.
Most molecules disappear before even entering the animal.
When plants grow, energy from (a) changes (b) and carbon dioxide molecules into food matter.
Which environments will NOT produce healthy plants?
Environment 1
Environment 2
Environment 2
Environment 3
Environment 3 only
Each of the environments will produce healthy plants.
