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. The edge of the continent






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






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






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






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






6. 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






7. Water layer that gets little or no light






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






9. Arid regions that are the dryest place on earth






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






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






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






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






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






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






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






18. The movement of gas molecules in the air






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






20. 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






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






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






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






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






25. A community and its abiotic environment






26. 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






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






28. A group ofi interacting populations






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






30. 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






31. Climate patterns that have warm summers and cold winters






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






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






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






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






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






37. Fancy way of saying underwater zones






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






39. 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






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






41. Animals that live togehter in intimate personal associatoin






42. Climate pattern located further north in Canada and Russia






43. 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






44. Tide caused when the Moon is on directly overhead on the other side of the 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. A group of members of the same species found in the given environment at a given time






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






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






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






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