25 Questions

1. 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

2. 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

3. Climate pattern with consistently cold temperatures

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

5. 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

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

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

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

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

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

11. 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

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

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

14. Animals that live togehter in intimate personal associatoin

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

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

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

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

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

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

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

22. 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

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

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

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