Across
- 1. - the geographic location based on direction faced, soil moisture, temperatures and soil type
- 5. - evaporated water from plants
- 6. - an organism that decomposes or breaks down dead or decaying organisms, returning the nutrients to the earth
- 7. - the significant lasting change in weather patterns over an extended period of time, natural disasters, coral bleaching, extinction
- 8. - born in water with gills to breathe but when older they develop lungs and can breathe out of water
- 9. - the number and variety of organisms (flora and fauna) found within a specified area. This will be determined by the factors of climate, geology and position and aspect. The variability among living organisms from all sources, including diversity within species and entire ecosystems
- 11. - movement of water through the ground to the water table
- 12. - deposits of petroleum, coal or natural gas, accumulated from ancient animals and plants
- 13. - what happens during the day and night and how that changes an ecosystem
- 19. - exchanging carbon dioxide for oxygen
- 21. - animal drinks milk from mother, births live young
- 23. - gain energy from eating a variety of sources
- 24. - animals that don’t have a backbone
- 26. - movement and change from water from a liquid to a vapour into the atmosphere
- 27. - movement of water across the surface into water storages or ways
- 28. - the rise and fall of sea levels, caused by a combined effect of the gravitational forces exerted by the moon, sun and the rotation of the earth
- 31. - process by which plants and some bacteria use the energy from sunlight to produce glucose and oxygen from carbon dioxide and water
- 33. - animals that have a backbone
- 35. - any animal that has more than 4 joined legs (insects and spiders)
- 39. - consumes plant based materials
- 40. - a prolonged, abnormally dry period when the amount of available water is insufficient to meet our normal use, doesn’t mean low rainfall, it is measured by the availability of water
- 43. - a specific place within an ecosystem occupied by an organism or population
- 46. - the living organisms in an ecosystem
- 47. - lays eggs but has no pouch, excretes milk through the skin
- 48. - consumes animals
- 51. - climatic change and movements in the earth's crust can cause large scale natural changes to occur, some biotic and abiotic factors can result in sudden changes (natural disasters)
- 54. - individual plants and animals consistently grow, develop, reproduce, die and decompose
- 55. - carnivores or omnivores, gain energy from eating herbivores
- 57. - cold blooded with scaly skin
- 58. - capture sunlight and convert it to energy via photosynthesis
- 59. - an interrelationship which demonstrates the flow of energy being passed from the sun to the producer to the consumer in order of hierarchy
- 60. - air
Down
- 2. - bacteria changing nitrogen in soil to a usable form, plants use this to build proteins
- 3. - the prevailing weather conditions of a region including annual rainfall, extremes in temperature, daylight hours, frost and snow and droughts and floods.
- 4. - waste and dead organisms decompose and release nitrates into the soil, bacteria then breaks this down and releases it into the air as gas
- 10. - herbivores, gaining energy from eating producers
- 14. - the physiological process that enables animals to exchange oxygen for carbon dioxide
- 15. - the ecosystems present in a location(s)
- 16. - when a community establishes itself where it has never been before. Eg. volcano, sand dune, glacier, introduced species
- 17. - born from a shell, have feathers
- 18. - one type of community can succeed another type. Natural changes in our plant communities are often referred to as a plant succession and result in vegetation being able to establish itself in an area without major disturbance
- 20. - consumes both plants and animals
- 22. - day/night, seasons, tides, flood, drought
- 25. - the species present in an ecosystem eg lizards, possums, wombats, frogs and echidnas
- 29. - soil, the Earth's crust and core
- 30. - the non living things in an ecosystem
- 32. - water released from the clouds as rain
- 34. - when a community that develops over time is similar to that of the original. Eg. fire, flood
- 36. - diversity within a species. Eg. how many different types of frogs
- 37. - from the highest mountain to the deepest ocean and everything in between, includes all forms of life on earth including their interactions
- 38. - the decaying processes releasing CO2 into the atmosphere
- 41. - water, oceans, icecaps, vapour
- 42. - the history and structure of the earth, can be seen in the rock material found in the location, soil characteristics, drainage and topography
- 44. - the formation of water droplets to form clouds
- 45. - a colourless, odourless gas, produced from the burning of fossil fuels
- 49. - change in weather patterns, summer, autumn, winter, spring
- 50. - a species that moves from one location to another in response to change in habitat, each is only suitable for part of their lives, linked to food availability, climate or breeding seasons
- 52. - effects can be devastating, river systems destroyed, habitat loss
- 53. - migration, succession, climate change
- 56. - vertebrates with gills and scales
