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






2. Classiciation order of species






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






4. Climate pattern located further north in Canada and Russia






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






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






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






8. Fancy way of saying underwater zones






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






10. A group ofi interacting populations






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






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






13. 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






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






15. 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






16. A community and its abiotic environment






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






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






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






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






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






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






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






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






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






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






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






28. Water layer that gets little or no light






29. Underwater mountain changes that form when plates move apart






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






31. The edge of the continent






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






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






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






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






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






38. 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






39. The edge of a continent that edges out underwater






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






41. 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






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






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






44. Animals that live togehter in intimate personal associatoin






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






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






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






48. The movement of gas molecules in the air






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






50. 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
