The best answer to fill in the blank is "multilayered membrane."
Temperature is considered an biotic limiting factor. The correct answer is A.
The pressure inside your lungs and the pressure outside them fluctuate as you breathe. An illustration of a pressure gradient is this.
<h3>What is an example of pressure gradient?</h3>
- The pressure gradient is the amount by which the atmospheric pressure drops in a location at a particular time.
- A pressure gradient is demonstrated by gale-force winds in one city changing to a moderate breeze after an hour. the rate of the pressure in space decreasing (gradient) at a specific period.
<h3>How does pulmonary ventilation change with pressure gradient?</h3>
Thoracic ventilation Because air moves down a pressure gradient, or from an area of greater pressure to an area of lower pressure, the difference in pressures is what drives pulmonary ventilation.
When breathing in and out, the respiratory airways restrict the flow of air. The air must be transported by the pressure gradient from the mount (or nose) to the pulmonary alveoli.

Answer:
D. Swamp
Explanation:
The photograph shows an ecosystem that is saturated by water. The plant species shown in the photograph are mostly trees and wooden species. These are characteristics of a swamp ecosystem. A swamp ecosystem is a wetland characterized by trees and wooden species. Therefore, the photograph shows a swamp ecosystem.
