  2. 3. Type of symbiosis where both species benefit.
  3. 6. The non-living components of an ecosystem (e.g., temperature, water, soil).
  4. 11. The process by which plants convert sunlight into chemical energy (food).
  5. 12. A linear sequence showing the transfer of energy from one organism to another.
  6. 14. A complex network of interconnected food chains in an ecosystem.
  7. 18. Interaction where one organism (predator) hunts and eats another organism (prey).
  8. 20. The process by which organisms use oxygen to break down food and release energy.
  9. 22. A diagram showing the amount of energy or biomass at each trophic level.
  10. 23. A group of individuals of the same species living in the same area.
  11. 26. A community of organisms interacting with their environment.
  12. 29. The living components of an ecosystem (e.g., plants, animals).
  13. 30. The process through which nitrogen is converted into different chemical forms, helping plants grow.

  1. 1. The process by which organisms better adapted to their environment survive and reproduce.
  2. 4. A trait or behavior that helps an organism survive in its environment.
  3. 5. The process through which carbon is exchanged among the atmosphere, organisms, and the Earth.
  4. 7. Struggle between organisms for limited resources.
  5. 8. The role or function of an organism within its ecosystem.

  7. 10. The variety of life forms in an ecosystem.
  8. 13. Species Non-native species that harm the ecosystem they invade.
  9. 15. Organism that eats other organisms for energy (e.g., animals).
  10. 16. Type of symbiosis where one species benefits and the other is not affected.
  11. 17. Organism that makes its own food, usually through photosynthesis (e.g., plants).
  12. 19. The process by which species change over time through natural selection.
