What would happen to the energy flow through an ecosystem of the decomposers were eliminated ?

Because decomposers release nutrients, if they were eliminated, wastes and and remains of dead organisms would pile up, and the left over organisms would never make it back to the ecosystem. Hope this helped, let me know if you need a little more assistance! :)

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .
