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. Arid regions that are the dryest place on earth






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






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






4. Climate patterns that have warm summers and cold winters






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






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






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






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






9. Fancy way of saying underwater zones






10. Located in the tropics where it remains warm and wet all year round and 2-9 inches of rain fall every year






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






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






13. Underwater mountain changes that form when plates move apart






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






15. 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






16. 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






17. A community and its abiotic environment






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






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






20. The edge of a continent that edges out underwater






21. A pattern of weather conditions determined by temperature - air pressure - precipitation






22. Climate pattern located further north in Canada and Russia






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






24. 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






25. A group ofi interacting populations






26. 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






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






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






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






30. 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






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






32. Classiciation order of species






33. 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






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






35. The consumption of one animal by another






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






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






38. Areas of ocean floor caused by converging tectonic plates and are deeper than those found on dry land






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






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






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






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






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






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






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






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






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






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






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






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