A lizard is an organism: An organism is a living thing and is a collection of organ systems (e.g. nervous, respiratory, circulatory, reproductive etc.)An organ system is a collection of organs e.g. reproductive system is made up of (in a female humans case) ovary, womb etc.An organ is a collection of tissues. e.g. the lungs are made up of different specialist tissues. some move mucus, others help the blood get close to the lungs etc.A tissue is made from a collection of similarly specialised cells, e.g. cilliated cells (ones with tiny hair-like things on the outside) lining your lungs A cell is a single building block (if you don't mind a Lego analogy) for the organism.
1. Respiratory system 2. Cardiovascular system
a organ systems are shared by both fish and birds because they have the same respiratory system, nervous system and reproductive system.

The excretory organ of agama lizard
The main organ in the respiratory system the lungs.
The lungs are the main organ of the respiratory system, but they are also an organ in the circulatory system.
the respiratory system
To gain oxygen and to lose CO2.
The main organ in the respiratory system the lungs.
To gain oxygen and to lose CO2.
Any animal that breathes has a respiratory organ
Because that is where the primary gas exchange happens.
This is the best explanation I could gather. Hopefully, this helped you. The respiratory system is responsible for taking in oxygen and eliminating waste gases like carbon dioxide. Because dogs and cats do not sweat through the skin, the respiratory system also plays an important role in the regulation of temperature.
the type of respiratory organ mollusks have is GILLS.
Compared to what? It is the only respiratory organ in humans.
