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






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






3. Classiciation order of species






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






5. Climate pattern located further north in Canada and Russia






6. Climate pattern with consistently cold temperatures






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






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






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






10. Climate patterns that have warm summers and cold winters






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






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






13. A community and its abiotic environment






14. Underwater mountain changes that form when plates move apart






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






16. A group ofi interacting populations






17. Animals that live togehter in intimate personal associatoin






18. The edge of the continent






19. Water layer that gets little or no light






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. 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






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






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






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






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






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






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






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






29. The consumption of one animal by another






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






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






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






33. 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






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






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






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






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






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






39. 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






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






41. 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






42. 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






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






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






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






46. The edge of a continent that edges out underwater






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






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






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






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