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
