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






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






3. Climate patterns that have warm summers and cold winters






4. The edge of the continent






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






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






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






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






9. 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






10. Arid regions that are the dryest place on earth






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






12. 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






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






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






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






16. The movement of gas molecules in the air






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






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






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






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






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






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






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






24. Fancy way of saying underwater zones






25. Water layer that gets little or no light






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






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






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. 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






30. Classiciation order of species






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






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






33. Underwater mountain changes that form when plates move apart






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






35. Climate pattern with consistently cold temperatures






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






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






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






40. 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






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






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






43. The consumption of one animal by another






44. 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






45. 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






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






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






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






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






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