Explanation / Answer
64. reservoirs. They are necessary for long term storage. others refer to living objects.
65. YES (Definitely, excessive industrial outflow causes acid spewing in atmosphere and gives acid rain, disrupting the sulfur cycle, for example.
66. True (Atmosphere= 78% Nitrogen, 21% Oxygen)
67. expansion of forests in the temperate zones - forests are decreasing in temperate zons, as they need cooler temperatures to survive)
68. detergents, fertilizers, and sewage treatment plants. - Cultural eutrophication occurs when man speeds up the aging process by allowing excessive amounts of nutrients in such forms as sewage, detergents, and fertilizers to enter the ecosystem. (Britannica)
69. Both are stored in fossil fuels. - organic compounds with nitrogen
70. TRUE . They break down the complex molecules into simpler forms and recycle them.
71. TRUE
72. Both are renewable energy sources. (They don't get exhausted)
73. the total amount of resources used by an individual to meet their needs - holistic thing, covers all other options
74. use nonporous surfaces for parking lots - water and air flow are impeded. To conserve, the surfaces should be POROUS
