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






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






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






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






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






6. Swampy areas of the taiga that are covered with dead plant matter






7. Fancy way of saying underwater zones






8. Climate patterns that have warm summers and cold winters






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






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






11. Underwater mountain changes that form when plates move apart






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






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






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






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






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






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






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






19. The consumption of one animal by another






20. Climate pattern located further north in Canada and Russia






21. The edge of a continent that edges out underwater






22. The edge of the continent






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






24. A group ofi interacting populations






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






26. 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






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






28. 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






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






30. 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






31. 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






32. Water layer that gets little or no light






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






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






35. 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






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






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






38. A group of members of the same species found in the given environment at a given time






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






40. 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






41. The movement of gas molecules in the air






42. Forest that has cold winters - warm sumers and moderate rainfall. Trees like maple - beech - oaks and willows and animals include fox - deer - woodchuck and squirrel






43. Classiciation order of species






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






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






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






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






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






49. The surface water that gets enough sunlight to support plants and animals called plankton






50. Popualation that colonizes a new habitat does not reflect the original gene pool of the original population
