Humans benefit greatly from the work of Pulmonary surfactant which reduces the surface tension in the alveoli of the lungs. This reduction in alveolar surface tension prevents the alveoli from collapsing and thus causing suffocation.
A common example of this type of relationship is commensalism, where one organism benefits from the association while the other remains unaffected. An example is the relationship between barnacles and whales, where barnacles attach themselves to whales to gain a stable surface for attachment, while the whales are not affected.
Commensalism is a type of symbiotic relationship where one organism benefits while the other is neither helped nor harmed. An example of commensalism is barnacles attaching themselves to the shell of a turtle. The barnacles gain a stable surface to live on and access to food particles in the water, while the turtle remains unaffected by their presence.
An example of an organism with spiracles is an insect, such as a grasshopper or a butterfly. Spiracles are openings on the surface of the exoskeleton that allow insects to breathe by facilitating the exchange of gases between the environment and their internal respiratory system.
The outside of an organism has a surface area.
Organisms need to have a high surface area to volume ratio to efficiently deliver nutrients. This allows for more surface area through which nutrients can be absorbed, reducing the distance that nutrients need to travel to reach cells inside the organism. This helps to maintain a balance between the intake of nutrients and the needs of the organism for growth and function.
If the surface area of the organism is small, then there is no problem with getting all the oxygen needed. If the surface area of the organism is large, therefore a special respiratory surface is needed. An example is lungs, gills. The ratio of surface area to volume in a small organism is greater than the ratio in a large organism.

tapeworm. They absorb nutrients directly through their body surface from their host organism, relying on the host for all essential nutrients. This is a classic example of a parasitic lifestyle where one organism benefits at the expense of another.
RadonSeal concrete sealer provides benefits such as preventing water damage, reducing mold growth, and strengthening the concrete surface.

By presenting small pieces of the organism on their surface
The outside of an organism has a surface area.
To decrease an object's surface area, you can alter its shape by making it more compact or reducing its dimensions. For example, transforming a flat object into a sphere or cube decreases the total surface area relative to its volume. Additionally, you can combine smaller objects into a single larger object, effectively reducing the overall surface area exposed to the environment.
The largest organism.
Organisms need to have a high surface area to volume ratio to efficiently deliver nutrients. This allows for more surface area through which nutrients can be absorbed, reducing the distance that nutrients need to travel to reach cells inside the organism. This helps to maintain a balance between the intake of nutrients and the needs of the organism for growth and function.
An example of an organism that absorbs food from the surface it lives on is a parasitic flatworm. These flatworms, also known as tapeworms, attach themselves to the intestinal lining of their host and absorb nutrients directly through their skin.
