“chemo” refers to energy source (reformed molecules)how the organism obtains electrons (from the oxidation and reduction-redox)
“organo”-refers to electron donor (organic substrate and compound)
“heterotroph”-refers to carbon source (organic compounds).
Examples of chemoorganoheterotrophs are decomposers-obtain carbon and electron reactions from dead organic matter, herbivores and carnivores- obtain carbon and electron reactions from living organic matter.

C. ACTING AS A SHOCK ABSORBER FOR THE BRAIN AND SPINAL CORD</h2>
Explanation:
Meninges are tissues that provide protection, support and also serve metabolic roles for the nervous system. The cerebrospinal fluid is the fluid of the central nervous system and serves as protection, gives buoyancy to the brain, assists in excretion of waste products of metabolism from the brain.
These meninges are of three membranes; the dura mater which is the outer membrane; the pia mater which is rich in blood vessels and the arachnoid mater which keeps the brain in the cerebrospinal fluid. The meninges, along with the cerbrospinal fluid serves to cushion the brain and spinal cord preventing shocks. The pia mater layer of the meninges provides for the delivering of oxygen directly into the CNS and protects the brain from infections through the action of the leucocytes in the blood.
Fungi break down dead matter while detritivores consume it.
Answer:
The CNS
Explanation:
First, the entire CNS is enclosed in bone. The brain is protected by the skull, while the spinal cord is protected by the vertebra of the spinal column. The brain and spinal cord are both covered with a protective tissue known as meninges.
