Anything that is considered alive must exhibit ALL 7 characteristics of life. A virus may show some characteristics, but it does not show all, so therefore, its not alive.
<span>The element Carbon is the </span>building block for all<span> known living things. That is why, in some science-fiction movies you hear the term, Carbon-based units.</span>
A, B, and C make no sense
A makes no sense because Methane is lighter than air, and so the Methane would stay higher in the atmosphere, so it would not seep into the ground, it would remain in the air.
B makes no sense because Burning fossil fuels causes air pollution by increasing the amount of carbon dioxide in the air. the only way that carbon dioxide could pollute water is if it is combined on a molecular level, plus carbon dioxide does not inhibit the process of water being evaporated by the sun.
C also makes no sense because Deforestation causes acid rain by increasing carbon dioxide not decreasing carbon dioxide in the atmosphere.
so therefore by elimination your answer is D
