CSET Ecology

Subjects : cset, ecology
  • 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 group of members of the same species found in the given environment at a given time

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

3. Water layer that gets little or no light

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

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

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

7. 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

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

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

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

11. 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

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

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

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

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

16. A community and its abiotic environment

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

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

19. Underwater mountain changes that form when plates move apart

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

21. Fancy way of saying underwater zones

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

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

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

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

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

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

28. 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

29. The edge of a continent that edges out underwater

30. Climate pattern with consistently cold temperatures

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

32. 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

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

34. Climate pattern located further north in Canada and Russia

35. The consumption of one animal by another

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

37. 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

38. A group ofi interacting populations

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

40. Classiciation order of species

41. 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

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

43. The edge of the continent

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

45. Climate patterns that have warm summers and cold winters

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

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

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

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

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