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 that is near the equator and always sunny and warm






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






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






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






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. Arid regions that are the dryest place on earth






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






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






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






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






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






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






13. A community and its abiotic environment






14. Climate patterns that have warm summers and cold winters






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






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






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






18. 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






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






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






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






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






23. Water layer that gets little or no light






24. 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






25. The edge of the continent






26. Climate pattern located further north in Canada and Russia






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






28. Underwater mountain changes that form when plates move apart






29. Climate pattern with consistently cold temperatures






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






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






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






33. The movement of gas molecules in the air






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






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






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






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






38. 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






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






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






41. The edge of a continent that edges out underwater






42. 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






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






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






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






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






47. The consumption of one animal by another






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






49. A group ofi interacting populations






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