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






2. Climate patterns that have warm summers and cold winters






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






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






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






6. Animals that live togehter in intimate personal associatoin






7. 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






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






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






10. The movement of gas molecules in the air






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






12. A community and its abiotic environment






13. Classiciation order of species






14. A group ofi interacting populations






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






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






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






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






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






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






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






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






23. 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






24. The consumption of one animal by another






25. Climate pattern located further north in Canada and Russia

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






28. The edge of a continent that edges out underwater






29. 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






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






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






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






33. 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






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






35. 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






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






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