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