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






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






3. Climate pattern with consistently cold temperatures






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






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






6. 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






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






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






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






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






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






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






13. The movement of gas molecules in the air






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






15. Fancy way of saying underwater zones






16. Classiciation order of species






17. Climate patterns that have warm summers and cold winters






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






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






20. The edge of the continent






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






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






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






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






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






26. 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






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






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






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






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






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






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






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






34. 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






35. 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






36. Animals that live togehter in intimate personal associatoin






37. A group ofi interacting populations






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






39. Climate pattern located further north in Canada and Russia






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






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






42. Water layer that gets little or no light






43. 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






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






45. A community and its abiotic environment






46. 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






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






48. The edge of a continent that edges out underwater






49. The consumption of one animal by another






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