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






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






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






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






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






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






8. The edge of a continent that edges out underwater






9. The edge of the continent






10. The movement of gas molecules in the air






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






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






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






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






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






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






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






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






19. Arid regions that are the dryest place on earth






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






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






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






23. 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






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






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






26. Climate patterns that have warm summers and cold winters






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






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. 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






30. A community and its abiotic environment






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






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






33. Climate pattern with consistently cold temperatures






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






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






36. A group ofi interacting populations






37. 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






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






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






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






41. 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






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






43. 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






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






45. Animals that live togehter in intimate personal associatoin






46. Fancy way of saying underwater zones






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






48. Small changesin a population's gene pool by random events






49. Climate pattern located further north in Canada and Russia






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