What are the functions of the larynx and how does it carry out them on a daily basis?
MArishka [77]
The larynx is an nicknamed the "voice box" because it holds the vocal cords inside. It helps change the pitch and volume of our voices as we speak. It is the only part of the body capable of doing this job, so we don't ever want it removed. Our voices would be much more monotone sounding. The larynx connects the pharynx to the trachea in the neck. It is also capable of allowing air through for us to breathe, but does not let anything (food or drink) block the airway. This is obviously a daily function since we eat and drink numerous times daily and usually have no problems breathing while eating and drinking. This is thanks to the larynx.

Hope this helps! :)

konstantin123 [22]
When energy passes from one trophic level to the next, I would guess that the two factors which decrease the total amount of energy from being passed up are: 
1. An organism does not assimilate all the energy of food consumed. Within a consumer, digestion and assimilation of energy is not 100% efficient: some of the energy is lost.
2. A large proportion of energy assimilated by a producer and consumer is lost through respiration, i.e., day-to-day maintenance of metabolic processes.
