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 a parasite takes from the host and gives nothing in return






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






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






4. Underwater mountain changes that form when plates move apart






5. Classiciation order of species






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






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






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






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






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






11. Climate pattern located further north in Canada and Russia






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






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






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






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






16. 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






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






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






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






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






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






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






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






24. Water layer that gets little or no light






25. 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






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






27. 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






28. A group ofi interacting populations






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






30. 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






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






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






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






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






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






36. 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






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






38. Animals that live togehter in intimate personal associatoin






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






40. Climate patterns that have warm summers and cold winters






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

47. The movement of gas molecules in the air






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






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