1. matter

2. molecules

3. cluster of atoms with unique characteristics

4. hydrocarbons

5. organic compounds

6. hydrogen and carbons

7. macromolecules

8. building block in life

9. proteins

10. made of aminoacid (monomers)

11. responsable of muscle contraction

12. carres oxygen in the body

13. carbohydrates

14. made of manosaccharides (monomers)

15. sugar and starches

16. short-term energy

17. lipids

18. made of glycerol and fatty acids

19. fats and oils

20. long-term energy

21. help create proteins

22. biochemical cycles

23. bio

24. living organism

25. geo

26. land

27. chemical

28. molecules reactions and atoms.

29. law of conservation of matter

30. matter transformed

31. not created

32. not destroyed

33. water cycle

34. water play a role in the enviornment

35. properties of water

36. cohesion

37. water molecules stick to themselves

38. expands when freeze

39. lebels of water cycle

40. Aquifers

41. condensation

42. evaporation

43. percipitation

44. surface renoff

45. groundwater

46. transpiration

47. carbon cycle

48. carbon

49. building block of llife

50. essential for DNA, fats, carbohydrates and more

51. carbon gas

52. carbon dioxide

53. help to maintain earth's temperature

54. stored in ocean, temperature and rocks

55. carbon sinks

56. place where a lot of carbon is stored

57. pathway 1

58. carbon moves between the atmosphere, ocean and living things

59. plants use CO2 of air and oceans to do photosynthesis

60. consumer eats plants, so carbons moves though food webs

61. with respiration carbon go directly to air

62. descomposition makes carbon returns to soil, water and air

63. pathway 2

64. carbon travels from living things to rocks, air and water

65. then livings things will be use it again

66. this process takes millions of years

67. pathway 3

68. formation and burning of fossil fuels

69. oils and natural gass for death organism

70. chemical change takes place and turns into petroleum

71. this process takes millions of years

72. when we burn the oil carbon dioxide release into the atmosphere so it may be able to plant to use it

73. human affected carbon dioxide

74. deforastation

75. removing trees that absorb carbon dioxide

76. burning of fossils fuels in industry and vehicles

77. the amount of carbon dioxide is been rising, and contributes to global warming

78. nitrogen cycle

79. nitrogen

80. important element in organic compounds

81. the most abundant gas in the atmosphere

82. the cycle is: from the atmosphere, to living things and then to the atmosphere again.

83. living things get nitrogen from the food.

84. living things can't use notrogen molecules they take it as a nitrate

85. nitrate is form then nitrogen is combinated with oxigen

86. nitrogen-fixing bacteria convert nitrogen into ammonia and then into nitrates.

87. plants used nitrates to make proteins

88. animals take nitrogen by eating plants

89. All material in the universe that occupies and space (has mass)

90. atoms

91. Smallest unit of a level

92. example: oxigen hydrogen,etc.

93. protons (+). neutrons (-)

94. organic compounds

95. have carbon

96. inorganic compounds

97. no carbon

98. nucleic acid

99. nucleotides (monomers)

100. DNA and RNA

101. molecules store genetic information

102. acids, bases and PH

103. biosphere

104. all living thins, once they are alive or death they still being part of the enviornment

105. abiotic

106. not living

107. biotic

108. living

109. geosphere

110. made up of rock

111. below earth's surface

112. lithosphere

113. hard rock

114. on and below earth's surface

115. atmosphere

116. gaseous envelop around the planet

117. hydrosphere

118. earth's supply of water

119. PH

120. to know how bases or asidic a solution is

121. humans alteres nitrogen cycle

122. fertilizers contain nitrogen, placed in the law

123. destruction of forest

124. burning of fossils fuel

125. phosphorus cycle

126. not a gas, don't enter the atmosphere

127. the cycle is: start on land, then to ocean and finally land again

128. water take it from the rocks and then leave it the soil plants root cant absorb it

129. makes DNA animals to take phosphate from the food.

130. oxygen cycle

131. photosynthesis and respiration

132. opposite reactions

133. plants produce oxygen with the process of photosynthesis

134. animals take oxygen and release carbon dioxide with the process of respiration
