some animals, but not humans have an organ called a gizzard located near the top of their digestive tract. this organ is small and can contain small rocks. it also has thick muscular walls. based on this physical description which of the following is most likely to be the function of this organ
a:chemical digestion
b:mechanical digestion
c:absorpition of water
d:absorpition of nutrients
please I need help!!!

the answer was b
Yes.
Based on the physical description provided, the most likely function of the organ described - small, containing small rocks, and having thick muscular walls - is mechanical digestion.
Mechanical digestion is a process that breaks down food into smaller pieces by physically grinding and crushing it. This helps animals, such as birds or some reptiles, who possess a gizzard to effectively break down tough food items, like seeds or insects, that require extensive mechanical processing.
To analyze and answer this question yourself in the future, it is crucial to understand the functions of different organs and their related physical characteristics. In this case, knowing that the gizzard is a small organ containing small rocks and has thick muscular walls can help you deduce its role in the digestive process.
