| Question | Answer |
|---|---|
| Parasitism | Form of symbiosis in which one member benefits and one is harmed (e.g., a leech attaches to a river turtle to suck its blood) |
| Indirect Relationship | e.g., fox eats all rabbits, gardens flourish |
| Direct Relationship | e.g., fox eats rabbit |
| Prey-predator Relationship | one organism "eats" another |
| Ecosystem | System formed by the interaction of a community of organisms with their environment (e.g., tundra, swamp, rain forest) |
| "Eco"logy (environment) | Study of the living and nonliving parts of an environment, and how they affect each other. |
| Scavenger | An organism that eats dead organism (e.g., turkey vulture, flies, lobsters) |
| Population | Number of organisms (of a species) that lives in a specific area (e.g., 2,000 white tailed deer in Buckfield) |
| Symbiosis | Relationship of 2 organisms that live in direct contact with one another |
| Niche | The roll ( job) and organism plays within its community ( e.g., tree provides oxygen for air to breath, shelter, food, etc.) |
| Community | Producers consumers + decomposers that live and interact with each other ( e.g.,, in a forest; deer, trees, birds,rabbits, and mushrooms) |
| Producers | An organism that makes its own food via photosynthesis or chemosynthesis ( e.g., dandelion, pine tree, cactus) |
| Consumers | An organism that can not make its own food, also has to obtain food via ingestion and absorption ( e.g., lion, jared) |
| Habitat | Where an organism lives ( e.g., pine tree lives in coniferous forest) -specific part if the ecosystem where a specific organism lives |
| Decomposer | An organism the breaks down organic material to sustain life (e.g., fungi, bacteria, earth worms) |
