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 consumption of one animal by another






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






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






5. Animals that live togehter in intimate personal associatoin






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






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






8. Arid regions that are the dryest place on earth






9. A group ofi interacting populations






10. 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






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






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






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






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






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. The edge of a continent that edges out underwater






17. 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






18. Classiciation order of species






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






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






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






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






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






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






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






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






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






28. Climate pattern with consistently cold temperatures






29. Water layer that gets little or no light






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






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






32. 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






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






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






35. 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






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






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






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






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






40. The edge of the continent






41. Climate pattern located further north in Canada and Russia






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






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






44. A community and its abiotic environment






45. The movement of gas molecules in the air






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






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






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






49. 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






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