| Term | Definition |
|---|---|
| Ecology | the study of living things and their environment |
| Ecosystem | all organisms in an area and the place they live |
| Biotic +2 factors | the living parts of an ecosystem Ex: plants and animals |
| Abiotic +6 factors | the non living parts of an ecosystem Ex: sun, temperature, rocks and soil, climate, water cycle atmosphere |
| Producer 3 types of producers | organisms that use energy from the sun or other chemical reactions to make their own food. Ex: plants, algae, and Cyanobacteria |
| Consumer (Some examples) | Organisms that cannot make their own food Ex: animals and protozoans |
| Decomposers (Some examples) | Organisms that break down dead animals, organisms, droppings, leaves, and other wastes produced by living things Ex: bacteria, protests, and insects |
| Photosynthesis | a process that producers use to make their own food using energy from sunlight |
| What starts the energy flow? | the sun |
| Herbivore (Some examples) | Organisms that only eat plants Ex: rabbits, elephants, and caterpillars |
| Carnivore (Some examples) | Organisms that only eat meat Ex: Venus fly trap, spiders, and sea anemones |
| Omnivore (Some examples) | Organisms that feed on other animals and plants Ex: grizzly bears and raccoons |
| Scavenger (Some examples) | Organisms that feed on dead animals Ex: crowd, vultures, and foxes |
| Food web | A more complicated model of how energy flows. Consists of many overlapping food chains in an ecosystem |
| Energy pyramid | shows how much energy is available that each type of consumer contains. |
| Food chain | a series of events in which one organism eats another and obtains energy. It shows how energy flows in one ecosystem. |
| Trophic levels | the position an organism occupies in a food chain |
| 3 biomes if California | the desert, chaparral, and temperate deciduous forest |
| Water cycle | the process by which water moves through the environment |
| Condensation | the part of the water cycle of when gas turns into a liquid |
| Precipitation | rain sleet hail or snow |
| Evaporation/transformation | when water transforms into gas and evaporation also purifies water |
| Carbon cycle | Describes how carbon moves between the living and non living environment |
| Nitrogen cycle | describes how nitrogen moves from the atmosphere to the soil to living organisms and back to the atmosphere |
| Prey | an animal that is hunted and killed for by another |
| Predators | an animal that naturally preys on others |
