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






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






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






4. A group ofi interacting populations






5. The edge of a continent that edges out underwater






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






7. 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






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






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






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






11. Water layer that gets little or no light






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






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






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






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






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






17. Animals that live togehter in intimate personal associatoin






18. 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






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






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






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






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






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






24. The edge of the continent






25. 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






26. Arid regions that are the dryest place on earth






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






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






29. Classiciation order of species






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






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






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






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






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






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






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






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






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






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






40. 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






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






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






43. Climate pattern with consistently cold temperatures






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






45. The movement of gas molecules in the air






46. 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






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






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






49. Climate patterns that have warm summers and cold winters






50. A community and its abiotic environment
