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. 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






2. Water layer that gets little or no light






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






4. Fancy way of saying underwater zones






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






6. 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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






24. The consumption of one animal by another






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






26. A group ofi interacting populations






27. Arid regions that are the dryest place on earth






28. Underwater mountain changes that form when plates move apart






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






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






31. Animals that live togehter in intimate personal associatoin






32. 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






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






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






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






37. Classiciation order of species






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






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






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






43. A community and its abiotic environment






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






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

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






48. The edge of a continent that edges out underwater






49. 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






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