- 5. animal who eats both plants and animals for energy, ex. humans
- 8. water is evaporated from land, other surfaces, and plants into the atmosphere
- 10. when liquid water warms and turns into water vapor
- 13. aquatic, photosynthetic microbes, responsible for the oxygenation of the Earth
- 15. prepares barren land for larger organisms, ex. lichens
- 17. evaporation of water from plants
- 18. when water vapor cools and becomes a liquid, opposite of evaporation
- 20. microscopic autotrophic organisms who play a key role in aquatic ecosystems; responsible for 70% of Earth’s oxygen
- 22. organisms who convert chemicals into food in the absence of sunlight
- 24. produce their own food using light or chemicals
- 26. organism who eats secondary consumers, typically the top of the food chain/web
Down
- 1. organism who eats primary consumers, have .5% of original energy
- 2. organism who consumes producers in the food pyramid, have 5% of original energy from the Sun
- 3. organisms who convert sunlight into food
- 4. animal who only consumes meat, other animals, ex. tigers
- 6. the mass of living biological organisms in a given area or ecosystem at a given time, subdivided into producers, primary consumers, etc.
- 7. make their own food, syn. autotrophs
- 9. when organisms take in oxygen and release carbon dioxide, breathing
- 11. organisms who break down dead organisms and waste and return nutrients to the soil
- 12. conversion of chemicals into food (glucose), typically done because of an absence of sunlight
- 14. organisms who eat other animals for food aka heterotrophs
- 16. conversion of sunlight into glucose, mainly used by land plants
- 19. triangle which shows how energy transfers from organism to organism
- 21. organism who obtains energy from dead plants and animals as well as fecal matter
- 23. when condensation makes clouds too heavy and water falls from the sky; depending on temperature, it can rain, snow, or hail
