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






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






3. 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






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






5. The movement of gas molecules in the air






6. Fancy way of saying underwater zones






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






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






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






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






11. 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






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






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






14. 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






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






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






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






18. Water layer that gets little or no light






19. Arid regions that are the dryest place on earth






20. A community and its abiotic environment






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






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






23. A group ofi interacting populations






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






25. 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






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






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






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






29. Animals that live togehter in intimate personal associatoin






30. The edge of the continent






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






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






33. 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






34. The consumption of one animal by another






35. The edge of a continent that edges out underwater






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






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






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






39. 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






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






41. Climate pattern with consistently cold temperatures






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






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






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






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






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






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






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






49. Climate patterns that have warm summers and cold winters






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