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. 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






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






3. Animals that live togehter in intimate personal associatoin






4. Climate pattern with consistently cold temperatures






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






6. The edge of a continent that edges out underwater






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






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






9. Water layer that gets little or no light






10. 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






11. Fancy way of saying underwater zones






12. The edge of the continent






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






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






15. 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






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






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






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






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






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






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






22. Climate pattern located further north in Canada and Russia






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






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






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






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






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






28. The movement of gas molecules in the air






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






30. Underwater mountain changes that form when plates move apart






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






32. Climate patterns that have warm summers and cold winters






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






34. 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






35. 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






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






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






38. The consumption of one animal by another






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






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






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






42. A group ofi interacting populations






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






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






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






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






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






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






49. 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






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