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






2. Animals that live togehter in intimate personal associatoin






3. Climate pattern located further north in Canada and Russia






4. Fancy way of saying underwater zones






5. The consumption of one animal by another






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






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






8. 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






9. Climate patterns that have warm summers and cold winters






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






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






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






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






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






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






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






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






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






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






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






22. 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






23. 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






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






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






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






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






28. Underwater mountain changes that form when plates move apart






29. 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






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






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






32. 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






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






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






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






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






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






38. The edge of the continent






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






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






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






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






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






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






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






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






47. A community and its abiotic environment






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






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






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