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. Fancy way of saying underwater zones






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






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






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






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






6. Underwater mountain changes that form when plates move apart






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






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






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






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






11. The edge of the continent






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






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






14. Animals that live togehter in intimate personal associatoin






15. 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






16. 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






17. The edge of a continent that edges out underwater






18. Classiciation order of species






19. 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






20. 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






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






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






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






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






25. Climate patterns that have warm summers and cold winters






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






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






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






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






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






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






32. 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






33. Water layer that gets little or no light






34. Climate pattern with consistently cold temperatures






35. 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






36. 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






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






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






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






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






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






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






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






44. Arid regions that are the dryest place on earth






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






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






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






48. Climate pattern located further north in Canada and Russia






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






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