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






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






3. 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






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






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






6. Arid regions that are the dryest place on earth






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






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






9. Animals that live togehter in intimate personal associatoin






10. The movement of gas molecules in the air






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






12. 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






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






14. Climate pattern with consistently cold temperatures






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






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






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






18. 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






19. A community and its abiotic environment






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






21. The edge of the continent






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






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






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






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






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






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






28. 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






29. Climate pattern located further north in Canada and Russia






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






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






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






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






34. Underwater mountain changes that form when plates move apart






35. 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






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






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






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






39. 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






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






41. 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






42. Classiciation order of species






43. Fancy way of saying underwater zones






44. Climate patterns that have warm summers and cold winters






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






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






47. The edge of a continent that edges out underwater






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






49. 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






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