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. Climate pattern located further north in Canada and Russia






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






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






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






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






6. A community and its abiotic environment






7. 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






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






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






10. 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






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






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






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






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






15. Climate patterns that have warm summers and cold winters






16. Animals that live togehter in intimate personal associatoin






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






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






19. Climate pattern with consistently cold temperatures






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






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






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






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






24. 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






25. The edge of the continent






26. Classiciation order of species






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






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






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






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






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






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






33. A group ofi interacting populations






34. Fancy way of saying underwater zones






35. Underwater mountain changes that form when plates move apart






36. 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






37. The movement of gas molecules in the air






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






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






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






41. 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






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






43. Arid regions that are the dryest place on earth






44. The edge of a continent that edges out underwater






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






46. 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






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






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






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






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