The four important characteristics of respiratory surface are:
1. Thin walls
2. Moisture
3. Large surface area
4. Blood supply
Respiratory system or respiratory tract is divided into upper and lower tract. Upper respiratory tract includes nose and its cavities, sinuses, pharynx and the part of the larynx. Lower respiratory tract consists of the trachea, bronchi, bronchioles and the alveoli.
Alveoli are the ends of the respiratory tract the smallest units in it. Alveoli are small folded air sacs that are branching off from alveolar ducts and providing an extremely large surface area for the gas exchange. Gas exchange occurs thanks to small blood vessels – capillaries that surround alveoli and it occurs via the process of diffusion.
So, respiratory surface is thin membrane also known as the blood–air barrier that consists of the alveolar epithelial cells, their basement membranes and the endothelial cells of the alveolar capillaries.

Answer:
E. climax
Explanation:
Even though it is not something that is very common in nature, there are still certain exceptions where certain communities manage to reach a point of equilibrium. This basically is a community of small number of dominant prominent species that create a stable ecosystem. This state of equilibrium is known as climax community. This type of community appears when the web of biotic interactions between the organisms becomes so intricate that there is no possibility of other species to be admitted in it.
