Mature rainforests are close to equilibrium in terms of their effects [#permalink]
Mature rainforests are close to equilibrium in terms of their effects on atmospheric carbon dioxide, absorbing about the same amount of carbon dioxide as they release. However, the growing trees of new rainforests do remove carbon dioxide from the atmosphere, storing absorbed carbon dioxide in their woody biomass as they grow. In its first 20 years of growth, an average acre of new rainforest will remove a total of 75 tons of carbon dioxide from the atmosphere, and the biomass of an average acre of mature rainforest stores the equivalent of 109 tons of carbon dioxide.

Which of the following is most strongly supported by the statements given?

(A) Any mature trees living in an area of mature rainforest have little to no effect on the atmosphere. ~effect mentioned is on atmospheric carbon dioxide

(B) An average acre of rainforest in which tree growth has been going on for 10 years holds around 37.5 tons of carbon dioxide. ~ calculate the average, wrong

(C) The older a tree, the less carbon dioxide that tree absorbs over the course of a year. ~ Nothing about a tree is mentioned

(D) Within 20 years, the average acre of rainforest growing today, if allowed to grow naturally, will have had most of the effect on atmospheric carbon dioxide that that acre will ever have. ~ aligns

(E) If percentage of the atmosphere made up of carbon dioxide were higher, trees in the rainforest would mature faster.­ ~Not mentioned

Re: Mature rainforests are close to equilibrium in terms of their effects [#permalink]
­aligns with what? are you making the unwarranted assumption that there isn't any other technology that can be implemented in an acre of land that can have more effect on atmospheric carbon dioxide? what if you built a highly pollutant factory within an acre that releases more CO2 than what even most carbon-capturing rainforest can absorb? what if you built a carbon-capture technology that is more efficient than rainforests in that acre of land? the answer sounds like total BS
