The parasympathetic nervous system is characterized by the location preganglionic neurons and the short postganglionic axons near the organs they innervate. The preganglionic neurons would originate in the spinal cord or the brainstem while the postganglionic neurons would lie outside the CNS.

For most terrestrial ecosystems, pyramids of numbers, biomass, and energy are essentially the same-they have a broad base and a
GaryK [48]

Answer:

b. at each step, energy is lost from the system as a result of keeping the organisms alive

Explanation:

Generally Ecological pyramids helps to visualise  the structure of Ecosystem.Its diagrammatically showed  the relative amounts of numbers of organisms ,their energy, and  the amount of energy that is converted in living tissue  as usable mass (biomass) at different tropic levels.

Basically, large amount of energy is lost as energy flow from one tropic level to  another in an ecosystem. This can be explained with the second law of thermodynamics;<u>  </u><u>which states that in the conversion of energy from one form to another in a system, there is always a tendency towards disorderliness</u><u>.</u>That is the entropy changes  of  the universe   can never be negative.Relatively  in a biological system, this means that  energy is lost in metabolic process( glycolysis, chemeosmosis, assimilation, growth .......)  as heat, as organisms at one tropic level is consumed  by another at the next level, from the base to the peak of  these pyramids.

The amount of energy transfer efficiency  among the two successive tropic levels is obtained by <u>dividing the energy transfer at present tropic level</u> with<u> the energy transfer at previous tropic levels</u> and<u> mutiply the results by 100%</u> . This known  as Tropic level transfer efficiency(TLTE) .

The lower energy efficiency between successful  present and previous tropic levels  in these pyramids accounts for  the similarities.
