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 with consistently cold temperatures






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






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






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






5. Underwater mountain changes that form when plates move apart






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






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






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






9. A group ofi interacting populations






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






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






12. Classiciation order of species






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






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






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






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






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






18. 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






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






20. 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






21. The consumption of one animal by another






22. A community and its abiotic environment






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






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






25. 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






26. 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






27. Fancy way of saying underwater zones






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






29. The movement of gas molecules in the air






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






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






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






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






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






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






36. Animals that live togehter in intimate personal associatoin






37. 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






38. Arid regions that are the dryest place on earth






39. 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
