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. Animals that live togehter in intimate personal associatoin






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






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






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






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






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






8. 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






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






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






11. Classiciation order of species






12. 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






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






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






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






16. A community and its abiotic environment






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






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






19. Climate pattern with consistently cold temperatures






20. Arid regions that are the dryest place on earth






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






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






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






24. The consumption of one animal by another






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






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






27. 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






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






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






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






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






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






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






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






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






36. Climate pattern located further north in Canada and Russia






37. The movement of gas molecules in the air






38. 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






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






40. A group ofi interacting populations






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






42. 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






43. 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






44. Climate patterns that have warm summers and cold winters






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






46. Fancy way of saying underwater zones






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






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






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






50. 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
