1. biodiversity

1.1. genetic

1.2. species

1.3. ecosystem

2. endangerd species

2.1. a species that will soon die out if we do not change the thing we are doing to harm them

3. threatend species

3.1. not as bad as and endangerd species but but the species is at risk of being endangerd

4. biotic

4.1. Something that is living, was living or peices of a living thing.

5. hot spot

6. Trophic levels

7. Indicator species

7.1. Indicates when a ecosystem is not healthy

8. ecological succession

9. primary succession

10. secondary succession

11. pioneer species

12. climax community

13. limiting factors

13.1. limiting factors help keep our population under controll

14. carrying capacity

14.1. how much of a species an ecosystem can hold

15. population growth

15.1. how many people are in the population

16. population growth rate

16.1. how fast a population grows

17. exponential growth

17.1. total ammount of growth

18. J-curve

18.1. a regular good population growth this is what the human population is following

19. S-curve

19.1. starts out as a J-curve but then when carrying capacity is reached the population starts to go down

20. renewable resource

20.1. a resource that will not run out

21. Organsim

22. Population

23. biomes

23.1. tundra

23.2. desert

23.3. rainforest

23.4. temperate deciduous forest

23.5. coniferous forest

23.6. freshwater biome

23.7. marine biome

23.8. grassland/savannah

24. food chain

24.1. producer

24.2. primary consumer

24.3. tertiary consumer

24.4. decomposer

25. food web

25.1. many organsims and biotic factors can be connected and the transfer of energy can go to many differnt organisms

26. abiotic

27. community

28. Ecosystem

29. Biome

30. Water pollution

30.1. non-point source

30.2. point source

31. aquifer

31.1. most of our accesable freshwater comes from aquifers which are underground sources of water

32. desalination

33. water purification

33.1. when polluted water is cleanded, a large ammount of the world lives without purified water

34. Watershed

34.1. a place where runoff water drains to when it rains. There are 4 big watersheds in Pensylvania alone.

35. impermeable

35.1. an impermeable surface does not absorbe water

35.2. an impermeable surface could be concrete , blacktop, or other surfaces that do not absorbe water

36. runoff water

36.1. runoff water ussullay caries many non-point source pollutants that end up in our watersheds

37. wetlands

37.1. where aquatic life lives, this is a water based ecosystem

38. urbanization

39. Organic pollutant

40. inorganic pollutant

41. natural resource

42. nonrenewable resource

42.1. oil

42.2. coal

42.3. gas
