<u>Respiration</u>is not considered to be an animal behavior.
<h3>What is Respiration?</h3>
The respiratory system, also known as the respiration or ventilatory system, is a biological system in both plants and animals that consists of a variety of organs and structures that are employed for gas exchange.
Depending on the organism's size, environment, and evolutionary background, the anatomy and physiology that cause respiration vary widely.
In land animals, the respiratory surface is internalized as the lining of the lungs.
Gas exchange in the lungs takes place in millions of tiny air sacs, known as alveoli in mammals and reptiles and atria in birds.
The air is in close touch with the blood in these tiny air sacs because they have an abundant blood supply.

<h3><u>Processes that form different fossil types:</u></h3>
The remained parts and elements of an organism that live several years ago is called as fossils.
Due to natural processes like weathering, soil erosion and other geological activities fossils are hard to preserve.
Carbonization, permineralization, recrystallization and replacement are the fossil formation processes.
Carbonization is the chemical reaction forming the thin film of carbon of the organic material.
Permineralization includes the fossils of bones and teeth. The recrystallization process is responsible for changing the micro-structure of the organic materials to form the fossils.
