When an olfactory receptor is stimulated, a generator potential must be produced by the receptor <span>before it signals the brain that a change has occurred.
In order to reach the threshold of the cell, a graded potential must be generated by the neuron of </span><span> the olfactory receptor. At threshold, an action potential will be generated, referred to as the generator potential. The brain then receives this generator potential in order to decode it.</span>
The exchange of useful chemicals between organisms and their abiotic environment is an example of matter cycling.
<h3>What is the matter cycling?</h3>
Matter cycling refers to the cyclic movement of matter between biotic factors and abiotic factors.
This process (matter cycling) is fundamental for the survival of organisms and health of an ecosystem.
