Explain the role of organisms in the carbon cycle.

 

Organisms play an important role in the carbon cycle in the following ways. Animals obtain their carbon by eating plants; they release carbon in respiration. Micrororganisms (such as fungi and bacteria) return carbon to the environment when they decompose dead plants and animals.

Explanation:

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
