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. 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






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






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






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






6. Climate pattern with consistently cold temperatures






7. The edge of a continent that edges out underwater






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






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






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






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






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






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






14. Classiciation order of species






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






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






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






18. A group ofi interacting populations






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






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






21. Water layer that gets little or no light






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






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






24. The edge of the continent






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






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






27. 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






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






29. The movement of gas molecules in the air






30. 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






31. The consumption of one animal by another






32. A community and its abiotic environment






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






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






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






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






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






38. Arid regions that are the dryest place on earth






39. Underwater mountain changes that form when plates move apart






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






41. Climate patterns that have warm summers and cold winters






42. 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






43. Climate pattern located further north in Canada and Russia






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






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






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






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






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






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. 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
