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






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






3. 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






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






5. A group ofi interacting populations






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






7. Climate pattern located further north in Canada and Russia






8. A community and its abiotic environment






9. The movement of gas molecules in the air






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






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






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






13. 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






14. 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






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






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






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






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






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






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






21. The consumption of one animal by another






22. Climate pattern with consistently cold temperatures






23. Water layer that gets little or no light






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






25. 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






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






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






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






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






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






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






32. Animals that live togehter in intimate personal associatoin






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






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






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. 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






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






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






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






40. Arid regions that are the dryest place on earth






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






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






43. Underwater mountain changes that form when plates move apart






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






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






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






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






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