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 rainforest where bacteria and fungi break up dead leaves






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






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






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






6. The edge of the continent






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






8. 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






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






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






11. Climate patterns that have warm summers and cold winters






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






13. Animals that live togehter in intimate personal associatoin






14. Climate pattern with consistently cold temperatures






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






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






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






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






19. A group ofi interacting populations






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






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






22. Underwater mountain changes that form when plates move apart






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






24. Water layer that gets little or no light






25. 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






26. Classiciation order of species






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






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






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






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






31. Fancy way of saying underwater zones






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






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






34. The edge of a continent that edges out underwater






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






36. 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






37. The movement of gas molecules in the air






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






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






40. 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






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






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






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






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






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






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






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






48. 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






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






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