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






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






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






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






5. Arid regions that are the dryest place on earth






6. 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






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






8. The edge of the continent






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






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






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






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






13. 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






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






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






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






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






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






19. Water layer that gets little or no light






20. 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






21. Underwater mountain changes that form when plates move apart






22. Classiciation order of species






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






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






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. The movement of gas molecules in the air






28. 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






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






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






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






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






33. Fancy way of saying underwater zones






34. The edge of a continent that edges out underwater






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






36. Climate pattern with consistently cold temperatures






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






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






39. 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






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






41. Found on the edge of the North Pole - in parts of Greenland - Alaska - Canada - Europe and Russia. Covered in snow seven to eight months of the year. Animals include caribou - polar bears - arctic weasels - fox - hares and wolf






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






43. A group ofi interacting populations






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






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






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






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






48. 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






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






50. A community and its abiotic environment
