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. A community and its abiotic environment






2. 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






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






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






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






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






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






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






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






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






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






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






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






14. 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






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






16. Climate pattern with consistently cold temperatures






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






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






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






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






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






22. 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






23. 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






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






25. Water layer that gets little or no light






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






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






28. Fancy way of saying underwater zones






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






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






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






32. Climate patterns that have warm summers and cold winters






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






34. The consumption of one animal by another






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






36. Animals that live togehter in intimate personal associatoin






37. Arid regions that are the dryest place on earth






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






39. Classiciation order of species






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






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






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






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






44. 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






45. The movement of gas molecules in the air






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






47. Climate pattern located further north in Canada and Russia






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






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






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