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. 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






2. 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






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






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






5. 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






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






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






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






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






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






11. 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






12. Climate pattern located further north in Canada and Russia






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






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






15. 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






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






17. The edge of the continent






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






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






20. Underwater mountain changes that form when plates move apart






21. The edge of a continent that edges out underwater






22. Arid regions that are the dryest place on earth






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






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






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






26. A group ofi interacting populations






27. Climate patterns that have warm summers and cold winters






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






29. 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






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






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






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






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






34. Classiciation order of species






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






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






37. Animals that live togehter in intimate personal associatoin






38. Climate pattern with consistently cold temperatures






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






40. A community and its abiotic environment






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






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






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






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






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






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






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






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






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






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