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






2. Climate pattern with consistently cold temperatures






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






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






5. 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






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






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






8. The edge of a continent that edges out underwater






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






10. Water layer that gets little or no light






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






12. 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






13. Animals that live togehter in intimate personal associatoin






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






15. 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






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






17. 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






18. 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






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






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






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






22. A community and its abiotic environment






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






24. The edge of the continent






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






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






27. Underwater mountain changes that form when plates move apart






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






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






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






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






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






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






34. Fancy way of saying underwater zones






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






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






37. A group ofi interacting populations






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






39. Classiciation order of species






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






41. The movement of gas molecules in the air






42. 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






43. Arid regions that are the dryest place on earth






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






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






46. Tides formed when the Moon - Earth and Sun are in right angles of each other






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






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






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






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