Across
  1. 5. Relating to water environments, including oceans, lakes, rivers, and ponds.
  2. 6. The ability to do work or cause change, which organisms obtain from food to grow, move, and survive.
  3. 8. A community of living organisms (plants, animals, and microbes) and their non-living environment (soil, water, air) interacting as a system.
  4. 9. The non-living components of an ecosystem, including sunlight, water, air, soil, and minerals.
  5. 11. Organisms, like plants and algae, that create their own food through photosynthesis.
  6. 13. A coastal wetland flooded and drained by salt water brought in by the tides, home to many plants and animals.
  7. 15. The movement of energy from one organism to another through food chains and webs.
  8. 18. Organisms that eat other living things for energy, including herbivores (plant eaters), carnivores (meat eaters), and omnivores (both).
  9. 19. A vast body of saltwater that covers most of the Earth’s surface, containing diverse ecosystems.
  10. 20. A group of individuals of the same species living in a specific area.
  11. 23. Open areas dominated by grasses, with few trees, often found in regions with moderate rainfall.
  12. 24. Large, flowing bodies of freshwater that move from higher to lower ground, often feeding into lakes or oceans.
  13. 26. A sequence that shows how energy and nutrients flow from one organism to another in an ecosystem.
Down
  1. 1. A coastal area where freshwater from rivers meets and mixes with saltwater from the ocean.
  2. 2. The specific environment where an organism lives, providing food, shelter, and other resources.
  3. 3. Organisms, like fungi and bacteria, that break down dead plants and animals, returning nutrients to the soil.
  4. 4. The living components of an ecosystem, such as plants, animals, and microorganisms.
  5. 6. The action of consuming food to obtain energy and nutrients.
  6. 7. Large, still bodies of freshwater surrounded by land.
  7. 10. All the different populations of organisms living and interacting in a particular area.
  8. 12. Smaller bodies of still freshwater, often shallower than lakes.
  9. 14. The way in which two or more organisms or groups interact with each other.
  10. 16. Smaller, flowing bodies of freshwater, usually smaller than rivers.
  11. 17. Areas densely populated with trees and other plants, providing habitat for many animals.
  12. 21. Any living thing, including plants, animals, and microorganisms.
  13. 22. Relating to land environments, such as forests, deserts, and grasslands.
  14. 25. A complex network of interconnected food chains showing how different organisms are related through feeding relationships.
