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 located further north in Canada and Russia






2. The edge of a continent that edges out underwater






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






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






5. Animals that live togehter in intimate personal associatoin






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






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






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






9. 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






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






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






12. Water layer that gets little or no light






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






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






15. The consumption of one animal by another






16. The movement of gas molecules in the air






17. A group ofi interacting populations






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






19. Classiciation order of species






20. 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






21. 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






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






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






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






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






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






27. 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






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






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






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






31. 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






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






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






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






35. 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






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






37. Fancy way of saying underwater zones






38. Climate pattern with consistently cold temperatures






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






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






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






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






43. The edge of the continent






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






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






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






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






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






49. Arid regions that are the dryest place on earth






50. Underwater mountain changes that form when plates move apart
