| Abiotic | Non-living parts of an ecosystem (sun, water). |
| Biotic | Living parts of an ecosystem (ex: plants and animals) |
| Habitat | The place in which an organism lives within an ecosystem, provides for basic needs. |
| Population | All the organisms in an ecosystem that belong to the SAME species (ex: all of the black bears in a forest). |
| Community | All the different populations that live together in an area and interact. |
| Ecosystem | Living and non-living things that interact in a paricular area. |
| Limiting Factors | Environmental factors that prevents the increase of a population. |
| Predator | An organism hunts and kills others animals for food. |
| prey | An organism that predators feed upon. |
| Food Chain | One possible path along which energy can move through an ecosystem. |
| Food Web | Many overlapping food chains that can interact with each other. Always start with a producer (plant) |
| Producer | An organism that makes its own food by using sunlight, it is always the first organism in a food chain. Always a plant!! |
| Consumer | An organism that gets energy by feeding on another organism. |
| Decomposer | it breaks down wastes and dead organism and returns the raw material to the environment |
| Herbivore | Only eats plants |
| Omnivore | Eats both plants and animals. |
| Organism | One single living thing. |
| Competition | The struggle between organisms to survive in a habitat . . . to get sunlight to make food or water |
| primary consumer | eats producer (1st organism that eats, usually a herbivore) |
| Energy pyramid | Shows the amount of energy from one feeding level to another; most energy is at the bottom |
| Evaporation | When liquid water changes into water vapor (gas). |
| Precipitation | When liquid water falls back to the earth as rain, snow, or sleet. |
| Photosynthesis | Plants use Carbon-Dioxide and sunlight to make food and Oxygen |
| Carbon Dioxide - Oxygen Cycle | Plants give off Oxygen that animals need and animals give off Carbon dioxide that plants need |
| Parasitism | When an organism uses another organism for food, shelter and protection |
| Chlorophyll | Green pigment in plants that captures sunlight |
| Sun | the main source of energy for producers |
| Levels of organization in order from smallest to largest | organism, population, community, ecosystem |
| Food chains start with a ______. | producer |
| Carbon dioxide | the gas that animals pass to plants that is needed for photosynthesis |
| Roots | helps plants get water and does NOT go through photosynthesis because there is no chlorophyll |
| Stomata | small openings under a leaf where carbon dioxide enters |
| What level in an energy pyramid has the least amount of energy? | top |
| Energy flows through which organisms in a food chain? | producer to herbivore to carnivore |
| Which organisms have the most energy? | plants |
