<span>Fungi is a decomposer. They make enzymes that decompose the decaying matter while feasting on the nutrients of that substance. This is why that most fungi are useful because without them, the biomass would be crowded with dead matter. Other decomposers include bacteria and actinomycetes. hope it helps ;)

The events of inspiration begins with the;
Impulses are conducted on the phrenic nerve to muscle fibers in the diaphragm contracting them.
As the dome shaped diaphragm moves downward the thoracic cavity expands.
At the same time the external intercostal muscles may contract raising the ribs and expanding the thoracic cavity further.
The intra-alveolar pressure decreases
Atmospheric pressure greater than intra-alveolar pressure forces the air into the respiratory tract through the air passages.
The lungs fill with air.
Your experiment has an accurate outcome. The only variable that should be changing is what you have already determined to be the independent variable. All other variables must be controlled (sometimes called constant) in order to preserve the accuracy of the experiment and ensure that the only thing impacted the change in the dependent variable is directly caused by the independent variable.
