| Question | Answer |
|---|---|
| An organism's energy role is determined by | How it obtains energy and how it interacts with other organisms |
| Energy enters most ecosystems as | Sunlight |
| Some organisms use sunlight to make their own food in a process called | Photosynthesis |
| An organism that can make its own food (the first organism in a food chain) | Producer |
| Producers are the source of all the food in an | Ecosystem |
| An organism that obtains energy by feeding on other organisms | Consumer |
| Consumers that only eat plants | Herbivores |
| Consumers that eat only animals | Carnivores |
| Consumers that eat both plans and animals | Omnivores |
| A carnivore that feeds on dead organisms | Scavengers |
| Breaks down wastes and dead organisms and return the raw materials to the ecosystem | Decomposers |
| The moment of energy through an ecosystem can be shown in diagrams called | Food Chains and Food Webs |
| A series of events in which one organism eats another and obtains energy | Food Chain |
| Feeds on a producer | First Level Consumer |
| Feeds on a first level consumer | Second Level Consumer |
| Most produces and consumers are part of | Many Food Chains |
| Consists of the many overlapping food chains in an ecosystem | Food Web |
| An ______ may play more than one role in an ecosystem | Organism |
| All of the world's food webs interconnect in what can be thought of as a | Global Food Web |
| Shows the amount of energy that moves from one feeding level to another in a food web | Energy Pyramid |
| The most energy is available at the _______ _______ of the pyramid | Producer Level |
| As you move up the pyramid, each level has _____ energy available than the level below | Less |
| Only about ____% of the energy at one level in transferred to the next higher level | 10% |
| About ____% of the energy is used to the organism's life processes or is lost to the environment as heat. | 90% |
| The amount of energy available at the producer level limits the number of consumers that the ecosystem can support is called | Carrying Capacity |
| Storm water ponds help ____ and ____ settle out so they don't get into natural bodies of water in the watershed | Pollutants and Sediments |
