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. The edge of a continent that edges out underwater






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






3. The movement of gas molecules in the air






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






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






6. Climate pattern located further north in Canada and Russia






7. 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






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






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






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






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






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






13. 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






14. 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






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






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






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






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






19. A group ofi interacting populations






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






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






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






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






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






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






26. Classiciation order of species






27. Climate pattern with consistently cold temperatures






28. 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






29. Animals that live togehter in intimate personal associatoin






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






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






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






33. Fancy way of saying underwater zones






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






35. Climate patterns that have warm summers and cold winters






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






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






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






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






40. 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






41. 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






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






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






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






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






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






47. 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






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






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






50. The edge of the continent
