The is the innermost region of the brain. a. forebrain b. midbrain c. hindbrain d. brainstem

The correct answer is option D, that is, brainstem.  

The innermost region of the brain is known as the brainstem, which continues with the spinal cord. It is the part of the brain, which associates the cerebrum with the spinal cord. It comprises the medulla oblongata, pons, and the midbrain. The sensory and the motor neurons pass via the brainstem permitting for the transmission of signals between the spinal cord and the brain.  

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.    

there's no big difference.
