Across
  1. 2. – When organisms fight for the same resources (like food or space).
  2. 3. Factors – The living parts of an ecosystem (like animals, plants, and bacteria).
  3. 5. Depletion – Running out of things like food, water, or space due to overpopulation.
  4. 10. – When individuals leave a population.
  5. 11. Capacity - The number or organisms that a particular habitat may sustain
  6. 12. Cycle – The way predator and prey populations go up and down together.
  7. 14. Factors – The non-living parts of an ecosystem (like sunlight, water, and temperature).
  8. 15. Factors – Things that affect a population no matter its size (like wildfires or floods).
  9. 18. – A symbiotic relationship where one species benefits, and the other is harmed (e.g., ticks on a dog).
  10. 22. – Cutting down too many trees, which destroys habitats.
  11. 23. – A group of the same species living in one area.
  12. 24. – A symbiotic relationship where both species help each other (e.g., bees and flowers).
  13. 28. – A close relationship between two species.
  14. 30. Cycle – How nitrogen moves between the air, soil, and living things.
  15. 32. – Harmful substances in the air, water, or land that hurt the environment.
  16. 33. factors -are things that affect a population more as it grows
  17. 35. – The role an organism plays in its environment (like what it eats and where it lives).
  18. 36. – The growth of cities, which can harm natural habitats.
  19. 37. Respiration – How cells turn food into energy.
  20. 38. – A community of living things and their environment.
  21. 39. – When a population grows super fast without limits.
Down
  1. 1. – How plants use sunlight to make food.
  2. 4. – When one organism (predator) hunts and eats another (prey).
  3. 6. – A symbiotic relationship where one species benefits, and the other is unaffected (e.g., barnacles on whales).
  4. 7. – When individuals move into a population.
  5. 8. Level – A step in a food chain (like producers, herbivores, and carnivores).
  6. 9. – The variety of different living things in an area.
  7. 13. Rate (Natality) – How many new individuals are born into a population.
  8. 16. Rate (Mortality) – How many individuals die in a population.
  9. 17. – The place where an organism lives.
  10. 19. Web – A bunch of connected food chains showing who eats what.
  11. 20. Change – Long-term changes in weather patterns, often caused by humans.
  12. 21. Pyramid – A diagram showing how energy moves through a food chain (with the most energy at the bottom).
  13. 25. Species – A species that moves into a new area and harms the ecosystem (like pythons in Florida).
  14. 26. – Using natural resources in a way that won’t run out.
  15. 27. Cycle – How carbon moves through the environment, including breathing and burning fuels.
  16. 29. – When population growth slows down as resources run out.
  17. 31. Dynamics – How a population changes in size and makeup over time.
  18. 34. Species – A species at risk of disappearing forever.
