Answer:
A decrease in biodiversity causes a decrease in ecosystem stability, because a change to one organism will have a greater impact on the entire ecosystem. With greater biodiversity, the loss of one type of organism could be moderated by the adaptation of other organisms to fill its role.

Answer:
C. When the chest volume expands, air can now rush in through the puncture without filling the alveoli.
Explanation:
During inhalation, the contraction of the diaphragm and the external intercostals increase the volume of the chest cavity. As the chest cavity expands, the alveolar pressure become lower than the atmospheric pressure resulting in the flow of air into the lungs in response to the pressure gradient.
The chest cavity is an airtight chamber. This ensures that any changes in the volume of are chest cavity corresponds to the volume of the lungs. If a lung is punctured, the air would not fill the punctured lung but would escape through the hole. Therefore, the punctured lung would not be filled with air during inhalation.
