The lungs remain inflated because intrapleural pressure is less than intrapulmonary pressure.

A sub-atmospheric intrapleural pressure that is lower than the intrapleural pressure results from the absence of air in the intrapleural space. The difference between intrapleural pressure and intrapleural pressure, known as transpulmonary (or transmural) pressure, is therefore present across the lung's wall. Transpulmonary pressure holds the lungs against the chest wall because intrapleural pressure—the pressure inside the lungs—is higher than intrapleural pressure—the pressure outside the lungs. As a result, during inspiration and expiration, changes in lung volume coincide with changes in thoracic volume.

The ocean is a carbon sink, with carbon being utilized by photosynthesis of phytoplankton describes the availability of carbon in the ocean and its use by marine processes

The ocean is a carbon sink, with carbon being utilized by photosynthesis of phytoplankton.

<u>Explanation:</u>

The carbon is found in the ocean is utilized by the phytoplankton found in the ocean. The carbon sinks in the ocean and then the process of photosynthesis required the carbon dioxide and the sunlight.

The ocean plays an important role in the carbon cycle, the carbon spreads in the ocean are called the ocean sink because it takes up more carbon from the atmosphere. The chemical and biological processes influence the carbon  by producing more carbon dioxide in the atmosphere.
