Across
  1. 2. Eats both plants and animals (e.g., humans, pigs).
  2. 3. Storage carbohydrate in chloroplasts/plastids
  3. 5. Plant/fruit reaches full size; seeds fully viable.
  4. 8. Water falling to Earth (rain, snow, hail).
  5. 11. Water vapour released from plant leaves.
  6. 12. Embryo in a protective coat; may be dormant.
  7. 14. Variety of life (genes, species, ecosystems).
  8. 15. All ecosystems on Earth.
  9. 17. Community + abiotic environment interacting.
  10. 20. Breaks down dead organisms/waste into simpler substances (e.g., fungi, many bacteria), recycling nutrients.
  11. 24. Pollen transferred to stigma (self or cross).
  12. 25. Interconnected food chains.
  13. 27. Organisms break down sugars, releasing CO₂.
  14. 30. Makes its own food (usually via photosynthesis; some via chemosynthesis).
  15. 32. Non-living components (light, temperature, water, pH, salinity, soil, nutrients).
  16. 33. – Leaves, stems, and roots expand (biomass increases).
  17. 34. Gets energy by eating other organisms/organic matter.
  18. 36. The place an organism lives.
  19. 38. Members of one species in an area.
  20. 39. – One organism kills/consumes another.
  21. 40. Seed absorbs water and begins growth.
  22. 41. Eats plants/algae only (e.g., koalas, cattle).
Down
  1. 1. – Organisms vying for the same resources.
  2. 4. Water vapour → liquid droplets (cloud formation).
  3. 6. A single pathway of energy flow.
  4. 7. set Fruits develop; seeds mature.
  5. 8. Plants/algae fix CO₂ into sugars using light.
  6. 9. Leaf pores for CO₂ in/O₂ out; control water loss (transpiration)
  7. 10. Water stored underground in soil/rock.
  8. 13. Eats other animals (e.g., dingoes, owls).
  9. 15. Living components (plants, animals, microbes) and their interactions.
  10. 16. Pollen nucleus fuses with ovule; seeds begin forming.
  11. 18. Microbes break down dead matter, returning CO₂ (or CH₄ in low-oxygen conditions).
  12. 19. All populations of different species in an area.
  13. 21. Water soaking into the soil.
  14. 22. Immediate product of photosynthesis; used in cellular respiration.
  15. 23. Eats dead organic matter fragments (e.g., earthworms, dung beetles); often aids decomposers.
  16. 26. Young plant forming first leaves and roots.
  17. 28. Water flowing over land to streams/rivers.
  18. 29. Open/close stomata in response to light, CO₂, water status.
  19. 31. Liquid water → water vapour from surfaces (lakes, soil).
  20. 35. Flowers develop and open.
  21. 37. Ageing; tissues break down; annuals die after seed set.
