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






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






3. A group ofi interacting populations






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






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






6. Climate patterns that have warm summers and cold winters






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






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






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






10. The edge of a continent that edges out underwater






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






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






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






14. Animals that live togehter in intimate personal associatoin






15. Arid regions that are the dryest place on earth






16. 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






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






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






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






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






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






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






23. Climate pattern with consistently cold temperatures






24. The movement of gas molecules in the air






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






26. A community and its abiotic environment






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






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






29. Water layer that gets little or no light






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






31. 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






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






33. 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






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






35. 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






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






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






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






39. The edge of the continent






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






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






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






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






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






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






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






47. The consumption of one animal by another






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






49. 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






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