What is a herbivore? Include 2 examples. | An animal that eats only plants Ex: rabbit and cow |
What is a carnivore? Include 2 examples. | An animal that eats only meat Ex: wolf and tiger |

What is a decomposer? Include 2 examples. | Breaks down dead food and animals and uses them for food. Ex: worm and bacteria |
Define metamorphosis. Include 2 examples. | A change in body form that some organisms go through Ex: butterflies and frogs |
What is the difference between a producer and a consumer? Give examples of each. | A producer makes its own food and a consumer does not. A consumer must eat something in order to survive. An example of a producer is a plant and a consumer is an animal. |
What is a predator? What is prey? | A predator hunts animals for food and prey is the animal that is being hunted. |
What is a food chain? Include an example. | A food chain is the food and energy links among producers and consumers in an ecosystem. Grass – Rabbit- Fox |
Describe adaptation and give an example. | A change or an adjustment to meet new conditions. Animals adapt to avoid enemies and to survive. An example is a bird flying south for the winter or a polar bear having a layer of fat. |
What is ecology? | The study of how plants and animals live together and interact with each other in their surroundings. |
What is an energy pyramid? | It is a model of energy flow in a community. Each level represents different organisms that might make up a food chain. Energy pyramids show how energy is moved from level to level. |
Describe how an increase or decrease in population of a certain animal affects the others in the same food chain. For example, mice and owls. | If the population of mice decreased, the owl population would decrease because there would be no food for the owl. If the mouse population increased, more owls would come to that area. |
What would eventually happen to all consumers if there were no more producers? Why? | If there were no more producers the consumers would all die because all food chains start with producers. Without producers, consumers can’t survive. |
