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






2. The consumption of one animal by another






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






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






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






6. Underwater mountain changes that form when plates move apart






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






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






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






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






11. Climate patterns that have warm summers and cold winters






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






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






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






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






16. The edge of a continent that edges out underwater






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






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






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






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






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






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






23. The edge of the continent






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






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






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






27. 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






28. 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






29. Fancy way of saying underwater zones






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






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






32. Climate pattern located further north in Canada and Russia






33. The movement of gas molecules in the air






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






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






36. A group ofi interacting populations






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






38. 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






39. Arid regions that are the dryest place on earth






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






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






42. 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






43. Classiciation order of species






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






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






46. 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






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






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






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






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