The structure that collects sound and funnels it into the auditory canal is called the pinna.
The ear is an exposed and sensitive organ in the human body. It is concerned with collecting, transmitting, and producing sounds. It also helps to maintain balance in the body. It has three main parts: the external ear, the middle ear, and the internal ear. Pinna is a part of the external ear.
Pinna is also called auricle. It is composed of cartilage folds that are covered by skin. The only part of the audible which is not covered by cartilage is the lobule. The curvature formed by cartilage is known as a helix. Another part of the pinna includes the meatus which is responsible for directing sounds collected by the helix.
Pinna acts as a link that transfers sound signals from the air to the auditory canal inside the ear. The tympanic membrane carries the sounds in an S-shaped path towards the middle ear (auditory canal).

Answer:
10%
Explanation:
The thermic effect of food is the calories burned for metabolizing the food eaten. Hence, thermic effect is estimated to be 10% of calories intake i.e. 10% of the calories taken within each meal are burned during the metabolism of food. the exact thermic effect of each meal may vary with the constituents of food taken as some food take more energy to metabolize while other take less energy to metabolize. For example, protein-rich foods such as meat, fish, poultry, dairy, legumes and seeds uses high energy content for metabolism and thus have higher thermic effect.
