| What are two names that describe organisms that can make their own food? | Producers, Autotrophs, 
|
| What are two processes that autotrophs use to produce their own food? | Photosynthesis, Chemosynthesis,
|
| What do you call organisms that can produce their own food without light? | chemosynthesizers,
|
Most chemosynthesizers are _______.,  | bacteria |
| Autotrophs use either light energy or chemical energy to produce ___. | carbohydrates,
|
| During photosynthesis, light energy is used to convert _____ and _____ into ____ and _____. | carbon dioxide and water into carbohydrates and oxygen,
|
| Another word for consumer is ____. | heterotroph,
|
| What are two words to describe organisms that must rely on other organisms for their energy and food supply? | Consumers, Heterotrophs,
|
| What do you call organisms that feed only on plants? | Herbivores,
|
| What do you call organisms that only feed on other animals? | Carnivores,
|
| What do you call organisms that feed on both plants and animals? | Omnivores |
| What do you call organisms that get energy by breaking down organic matter left over from dead organisms? | Decomposers |
| Describe how energy in an ecosystem moves? | It moves in a one-way path, from the sun or inorganic compounds, to producers and then consumers. |
| Describe how matter moves in an ecosystem? | Matter cycles through an ecosystem, going from producers to the consumers who eat the producers and eventually to decomposers who change the matter into forms the producers can use, to start the cycle all over again. |
| True or false? "Matter is used up in an ecosystem." | False, it keeps cycling from one type of organism to another. |
| True or False? "Energy is used up in an ecosystem." | True, energy travels in a one way direction, and is eventually lost as heat from the different organisms as it travels up the food chain. |
| A series of steps in which organisms transfer energy by eating or being eaten is called a ___. | food chain |
| _______ show the one-way flow of energy through an ecosystem. | Food chains |
| Which way do arrows point in a food chain? | They point from the organism that is being eaten towards the organism that eats them. They show which way energy is being passed along in an ecosystem.,  |
| A ______ describes the complex feeding relationships among all organisms in an ecosystem, including the decomposers. | food web |
| The picture below depicts a ____., | food chain, |
The picture below depicts a ____.,  | food web, |
