CSET Ecology

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






2. 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






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






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






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






6. The edge of a continent that edges out underwater






7. Caused by high pressure systems and cold ocean currents. Animals living in this climate have thick fur and a lot of fat to get them through the cold temperatures






8. Climate patterns that have warm summers and cold winters






9. When cold air pushes up warm air leading to violent storms






10. Climate pattern where it is hot and dry in the summer - col in the winter - four distinct seasons and wet in autumn






11. Water layer that gets no light at all at 6000 degrees below sea level






12. Animals that live togehter in intimate personal associatoin






13. Forest that is cold - dry and inhabited by fir - pine and have animals like moose - deer - bears - hares - wolves and porcupines






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






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






16. Underwater volcanic cones that eventually get large enough to form volcanic islands like Hawaii






17. The consumption of one animal by another






18. Found in Antarctica - tip of South America. Have soil that can hold lichens - mosses - ferns and other small tundra plants






19. Arid regions that are the dryest place on earth






20. 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






21. When a parasite takes from the host and gives nothing in return






22. Concept that allele frequencies remain constant from generation to generation as long as 1. random mating has occurred so that there is no dominant gene - 2. iommigration and emigration does not take palce - 3. no mutations - 4. large population pres






23. The ocean floor and includes coral reefs to continental shelves - underwater mountain ranges - and deep ocean trenches






24. A combination of populations that do not chanage the environment any further and leave the community stable over time unless the climax community is disturbed






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






26. 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






27. A symbiotic relationship where both organisms derive some benefit - like the rhino and the bird






28. The edge of the continent






29. Fancy way of saying underwater zones






30. Climate patterns that receive less than 25 cm of rain per year including deserts






31. Climate patterns that have various temperature ranges and are located in the northern hemisphere






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






33. Water layer that gets little or no light






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






35. Classiciation order of species






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






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






38. Climate pattern with consistently cold temperatures






39. Climate pattern located further north in Canada and Russia






40. Layer of the rainforest made up of shorter trees - bushes and ferns






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






42. A community and its abiotic environment






43. Cover only 7 percent of the earth's surface but contain more than 50 percent of its biology






44. A group ofi interacting populations






45. Climate pattern that is near the equator and always sunny and warm






46. Creation of a new species when the gene pool for a group of organisms is isolated






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






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






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






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