The overuse of chemical fertilizers has resulted in the growth of some lawns in which decomposers cannot live. this would interfere most directly with the ability of the lawn ecosystem to
(1)recycle energy
(2)recycle nutrients
(3)maintain atmospheric ph
(4)reduce biodiversity

With the overuse of chemical fertilizers, many lawns now have it to where decomposers can't live. This interferes most directly with the lawn ecosystem to recycle important nutrients. The correct answer is choice number 2.
