| An organism's _____ provides food, water, shelter and space. | habitat |
| All energy comes from the_____ , and then cycles through the food webs to all of the animals in the community. | sun |
| _______ get energy directly from the sun and use it to make food. | plants |
| Because plants produce their own food, they are called ___________ . | producers |
| Organisms that get their energy from eating plants or other animals are called: | consumers |
| All of the interrelated food chains in an ecosystem make up a: | food web |
| Food chains and food webs always start with a: | plant |
| The food chain starts with a producer (a plant) and ends with a: | decomposer |
| Decomposers like ______ break down organisms and recycle them back to the nutrient pool. | fungi |
| All of the living and nonliving things in an environment make up an: | ecosystem |
| the role an oraganism plays in its environment | niche |
| All organisms have _________ that allow it to survive in its environment | adaptations |
| Structural adaptations are __________ that help an organism survive, like long beaks, webbed feet, camouflage. | body parts |
| Behavioral adaptations are things that organisms do to survive. Two examples of behavioral adaptations are: | Migration and hibernation |
| The measure of the amount of heat energy in the atmosphere is: | temperature |
| The amount of moisture in the air is: | humidity |
| The weight of the air causes: | air pressure |
| Objects in motion have ______ energy. | kinetic |
| Potential energy is ________ energy. | stored |
| Due to the pull of gravity, the higher an object is off the ground, the more ____________ it has. | potential energy |
| When I hold a ball in the air, it has potential energy. When I let go, the ball starts to fall. Potential energy changes to: | kinetic energy |
| Potential energy is ________ energy. | stored |
| There are many forms of energy. Energy caused by the movement of electrons is: | energy |
| Energy stored in food, batteries and fossil fuels like coal and gasoline is: | chemical energy |
| Energy in moving or spinning objects like gears, car wheels, or joggers, is _______ energy: | mechanical |
| Two objects rubbing together create: | friction |
| Friction resists or stops motion, and creates: | heat |
| Unless acted on by a force, objects in motion tend to stay in motion and objects at rest remain at rest. This is the principal of: | inertia |
| Which will light a bulb, an open or closed circuit? | closed circuit |
| If your string of holiday lights goes dark when one little bulb burns out, the string of lights is a: | series circuit |
| This circuit has more than one pathway for the flow of electrical current. If one bulb burns the others will remain lit. It is a: | Parallel circuit |

| Material like rubber, plastic and wood do not conduct electricity well. They are: | insulators |
| Magnetism and _______ are very closely related. | electricity |
| An electric current creates a magnetic field, and a magnetic field creates an _________ | electric current |
