Animal kingdom
The highest level of organization in an animal is apparently the organ system. Just beneath that are the organs that make it up, the tissues that make those up, and the cells that make those up.
It is referred as a Taxon.Taxon- groups or level of organization in which organisms are classified.
The first level of organization are living cells. The second level of organization are tissues. The third level of organization is an organ. The fourth level of organization is the organ system. The last level is organisms.
The fourth level of cell organization is an organ system. The levels of organization are: Cell, Tissue, Organ, Organ system.

The organ system level is the fourth and highest level of organization in a multicellular organism. At this level, multiple organs work together to carry out specific functions, such as the circulatory system or digestive system.
The levels of organization in Anatomy and Physiology are: chemical level (atoms and molecules), cellular level (cells and their organelles), tissue level (groups of similar cells working together), organ level (combinations of different tissues working together), organ system level (organs working together to perform a common function), and organism level (full living individual).
