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






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






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






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






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






6. 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






7. The edge of a continent that edges out underwater






8. 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






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






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






11. Arid regions that are the dryest place on earth






12. 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






13. The movement of gas molecules in the air






14. 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






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






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






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






18. Climate pattern located further north in Canada and Russia






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






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






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






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






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






24. Climate pattern with consistently cold temperatures






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






26. The consumption of one animal by another






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






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






29. 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






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






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






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






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






34. Fancy way of saying underwater zones






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






36. Animals that live togehter in intimate personal associatoin






37. 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






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






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






40. Underwater mountain changes that form when plates move apart






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






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






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






44. A community and its abiotic environment






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






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






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






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






49. A group ofi interacting populations






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