  1. 3. energy source for plants to perform photosynthesis; starting energy source in food chains
  2. 4. a series of steps in which organisms transfer energy by eating and being eaten
  3. 7. chain represent the direction of energy transferred from one organism to another (ex. producer → consumer) (ex. herbivore → carnivore)
  4. 8. a substance that provides nourishment essential for growth and maintenance of life that is returned to the soil by decomposers
  5. 9. organisms that break down waste and dead organisms that return nutrients to the soil (ex. worms and fungi
  6. 11. A consumer that eats only plants (ex. cows and rabbits)

  11. 17. the energy produced from food sources which keeps animals warm, helps animals move, and allows animals to grow
Down
  1. 1. organisms that make their own food through photosynthesis; tropic level with the most energy in it (ex. trees and flowers)
  2. 2. a gas expelled by animals and used by plants during photosynthesis
  3. 5. A consumer that eats only animals (ex. lions and eagles)
  4. 6. Species species that normally live and thrive in a particular ecosystem
  5. 10. sugar created by plants during photosynthesis to help the plant grow
  6. 13. process by which plants use light energy to convert water and carbon dioxide into oxygen and glucose
