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






2. Climate pattern with consistently cold temperatures






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






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






5. Arid regions that are the dryest place on earth






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






7. The consumption of one animal by another






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






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






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






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






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






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






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






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






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






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






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






19. 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






20. 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






21. 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






22. 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






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






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






25. Underwater mountain changes that form when plates move apart






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






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






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






29. Climate pattern located further north in Canada and Russia






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






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






32. Classiciation order of species






33. 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






34. A group ofi interacting populations






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






36. The edge of the continent






37. Fancy way of saying underwater zones






38. Climate patterns that have warm summers and cold winters






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






40. The edge of a continent that edges out underwater






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






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






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






44. 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






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






46. 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






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






48. 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






49. Animals that live togehter in intimate personal associatoin






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