Subjects : cset, ecology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Forest that is cold - dry and inhabited by fir - pine and have animals like moose - deer - bears - hares - wolves and porcupines






2. One organism benefits from association and the other organism is not affected - like the sharpsucker on the underside of a shark






3. Arid regions that are the dryest place on earth






4. Climate pattern where it is cooler than the climate that the mountain is situated in






5. Fancy way of saying underwater zones






6. Layer of rainforest where bacteria and fungi break up dead leaves






7. A group of similar organisms that can produce viable - fertile offspring






8. A group ofi interacting populations






9. Leafy green top of the rainforest where all kinds of vines and plants grow






10. Found on the edge of the North Pole - in parts of Greenland - Alaska - Canada - Europe and Russia. Covered in snow seven to eight months of the year. Animals include caribou - polar bears - arctic weasels - fox - hares and wolf






11. When neither cold air nor warm air advances and clouds form on both sides of the front






12. An interdependent system of plants - animals - and land determined by rainfall - temperature - and altittude






13. The edge of the continent






14. Animals that live togehter in intimate personal associatoin






15. Water layer that gets little or no light






16. Tides formed when the Moon - Earth and Sun are in right angles of each other






17. A community and its abiotic environment






18. Tides formed when the Moon - Eaerth and Sun are aligned






19. Found on mountain tops above the tree line with heavy snowfalls and high winds






20. A layer of soil found in the tundra that stays below freezing






21. A belt of coniferous forests that stretches across most of North America - Asia and Europe






22. Tide caused when the Moon is on directly overhead on the other side of the Earth






23. Climate pattern where it is cool in the winter - warm during the summer and has four distinct season






24. Grasslands scattered with shrubs and trees found in tropical lattitudes 30 degrees north and south of the equator. Summers last six to eight months and are really wet and winters are hot and dry






25. Climate pattern found close to the equator and receive more sunlight than other areas






26. Tide caused when the Moon is directly overhead a part of the earth






27. Climate patterns in which the winters are not so cold and summers are hot; can be found near mediterranean seas






28. Experience when a natural disaster occurs and wipes out a portion of a population - the gene pool of the survivors is not the same as the original population






29. Hot regions located 30 degrees lattitude north and south of the equator and are hot because of a mixture of hot air press ure and capturing of sun rays which causes more evaporation. Animals in these landscapes sleep below ground or in the shade






30. Trees that make seed - bearing cones like pine and fir trees

34. Climate patterns that have warm summers and cold winters






35. When warm air replaces cold air leading to steady preciptiation






36. Climate pattern located further north in Canada and Russia
