  3. 6. – Consumer that eats strictly plants.
  4. 8. – Cold biome dominated by coniferous evergreen forests.
  5. 10. – Cold, treeless biome characterized by permanently frozen subsoil.
  6. 15. – Consumer that eats both plants and animals.
  7. 16. – Open biome dominated primarily by grasses rather than large trees.
  8. 17. – A group of organisms of different species interacting in an area.
  9. 18. – Water-based ecosystem such as ponds, rivers, or oceans.
  10. 21. – Decomposers alongside bacteria that release nutrients back to soil.
  11. 23. – Diagram showing interconnected feeding relationships in an ecosystem.
  12. 24. – Dry biome with extremely low annual rainfall.
