(N/A) Two possible consequences of the elimination of decomposers from the Earth are:
$(1)$ Accumulation of complex organic waste: Without decomposers,dead plants and animals would not be broken down into simpler substances. This would lead to the accumulation of organic waste,causing severe land,water,and air pollution.
$(2)$ Disruption of nutrient cycling: Decomposers are essential for recycling nutrients back into the soil. Without them,the soil would lose its fertility as essential minerals would remain locked in dead organic matter,preventing the growth of plants,which are the primary producers and the foundation of the ecosystem.
