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






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






3. Water layer that gets little or no light






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






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






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






7. 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






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






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






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






11. 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






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






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






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






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






16. A community and its abiotic environment






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






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






19. Underwater mountain changes that form when plates move apart






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






21. Fancy way of saying underwater zones






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






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






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






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






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






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






28. 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






29. The edge of a continent that edges out underwater






30. Climate pattern with consistently cold temperatures






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






32. 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






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






34. Climate pattern located further north in Canada and Russia






35. The consumption of one animal by another






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






37. 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






38. A group ofi interacting populations






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






40. Classiciation order of species






41. 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






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






43. The edge of the continent






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






45. Climate patterns that have warm summers and cold winters






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






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






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






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






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