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






2. 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






3. Climate patterns that have warm summers and cold winters






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






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






6. The edge of the continent






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






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






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






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






11. 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






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






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






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






15. Climate pattern located further north in Canada and Russia






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






17. 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






18. The consumption of one animal by another






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






20. A group ofi interacting populations






21. 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






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






23. 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






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






25. A community and its abiotic environment






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






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






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






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






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






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






32. Climate pattern with consistently cold temperatures






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






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






35. 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






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






37. Water layer that gets little or no light






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






39. Fancy way of saying underwater zones






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






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






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






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






44. Classiciation order of species






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






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






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






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






49. The movement of gas molecules in the air






50. 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
