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






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






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






4. Climate patterns that have warm summers and cold winters






5. The consumption of one animal by another






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






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






8. Arid regions that are the dryest place on earth






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






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






11. A group ofi interacting populations






12. Underwater mountain changes that form when plates move apart






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






14. Classiciation order of species






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






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






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






18. 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






19. The movement of gas molecules in the air






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






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






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






23. A community and its abiotic environment






24. Fancy way of saying underwater zones






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






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






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






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






29. Climate pattern with consistently cold temperatures






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






31. 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






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






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






34. Animals that live togehter in intimate personal associatoin






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






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






37. 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






38. The edge of the continent






39. 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






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






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






42. 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






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






44. 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






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






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






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






48. 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






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






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