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






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






3. 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






4. The consumption of one animal by another






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






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






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






8. The movement of gas molecules in the air






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






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






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






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






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






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






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






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






17. 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






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






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






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






21. Water layer that gets little or no light






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






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






24. The edge of a continent that edges out underwater






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






26. 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






27. A group ofi interacting populations






28. Fancy way of saying underwater zones






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






30. Climate pattern with consistently cold temperatures






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






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






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






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






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






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






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






38. Climate pattern located further north in Canada and Russia






39. Animals that live togehter in intimate personal associatoin






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






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






42. 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






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






44. Climate patterns that have warm summers and cold winters






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






46. 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






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






48. 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






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






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