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. The movement of gas molecules in the air






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






3. The edge of a continent that edges out underwater






4. Water layer that gets little or no light






5. Arid regions that are the dryest place on earth






6. Animals that live togehter in intimate personal associatoin






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






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






9. Climate pattern with consistently cold temperatures






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






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






12. 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






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






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






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






16. A community and its abiotic environment






17. Climate patterns that have warm summers and cold winters






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






19. 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






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






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






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






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






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






25. 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






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






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






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






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






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






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. Classiciation order of species






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






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






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






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






38. Fancy way of saying underwater zones






39. 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






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






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






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






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






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






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






46. 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






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






48. The consumption of one animal by another






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






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