The part of the experiment that a scientist manipulates or test
Independent Variable (test variable)
What type of energy is stored in food?
Chemical
What cannot NEVER happen to matter or energy?
It can never be created or destroys
On the pyramid what organisms make their own food?

What is the benefit f conducting an experiment vs. doing a field study.
control all the variables
The part of the experiment that gives results or measures.
Depending variable (outcome variable)
What do the arrows on a Food Web represent?
The flow/transfer of energy from one organism to another.
What are the 2 things that can happen to energy?
It can be changed to a different type or transferred into something else.
What level consumers are complete herbivores?

What is the benefit of a field study vs, an experiment?
able to observe in a natural habitat.
When considering variables which one is the cause and which one if the effect?
Independent is the cause
Dependent is the effect
How does a food chain help demonstrate the Law of Conservation of Energy?
Energy is transferred from one organism to another.
The Law of Conservation of Energy and Law of Conservation of Mass are very similar. However there is one major difference. Besides dealing with matter or energy what is the major difference?
Energy can be transferred matter cannot
On a standard energy pyramid, what level consumers would be at the top?

What 3 things are true of every model
They represent something else
They help make it easier to understand
They have benefits and limitations
On a food web model what organisms are the least likely to affect each other directly or indirectly?
Producers/ Plants
How does watching TV model 2 parts of The Law of Conservation of Energy?
Energy is transferred through the wires and energy changes type/form from electric to light and sound
What happens to most of the energy in the pyramid before it can transfer?
IT is used by organisms at lower levels.
