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






2. Underwater mountain changes that form when plates move apart






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






4. 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






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






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






7. Arid regions that are the dryest place on earth






8. The consumption of one animal by another






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






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






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






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






13. A community and its abiotic environment






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






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






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






17. 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






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






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






20. A group ofi interacting populations






21. 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






22. 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






23. 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






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






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






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






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






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






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






30. Water layer that gets little or no light






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






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






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






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






35. Classiciation order of species






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






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






38. The movement of gas molecules in the air






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






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






41. The edge of a continent that edges out underwater






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






43. Climate patterns that have warm summers and cold winters






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






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






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






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






48. The edge of the continent






49. 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






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