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






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






4. 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

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






7. A community and its abiotic environment






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






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






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






11. Climate pattern located further north in Canada and Russia






12. Classiciation order of species






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






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






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






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






17. Animals that live togehter in intimate personal associatoin






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






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






20. 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

32. The consumption of one animal by another






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






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

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






40. 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
