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






2. Water layer that gets little or no light






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






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






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






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






7. A group ofi interacting populations






8. 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






9. Arid regions that are the dryest place on earth






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






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






12. Fancy way of saying underwater zones






13. Classiciation order of species






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






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






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






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






18. The movement of gas molecules in the air






19. Climate pattern with consistently cold temperatures






20. The edge of a continent that edges out underwater






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






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






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






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






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






26. Climate pattern located further north in Canada and Russia






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






28. Animals that live togehter in intimate personal associatoin






29. 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






30. Climate patterns that have warm summers and cold winters






31. The edge of the continent






32. A community and its abiotic environment






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






34. 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






35. 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






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






37. 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






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






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






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






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






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






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






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






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






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






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






48. 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






49. The consumption of one animal by another






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