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. The edge of the continent






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






3. Animals that live togehter in intimate personal associatoin






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






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






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






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






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






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






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






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






12. Underwater mountain changes that form when plates move apart






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






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






15. The consumption of one animal by another






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






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






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






19. Fancy way of saying underwater zones






20. Climate patterns that have warm summers and cold winters






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






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






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






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






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






26. 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






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






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






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






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






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






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






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