Levels of organization are the way Biology is layered in a hierarchy. For example, organs make up one level, as the fourth level of organization.
The highest level in the organizational hierarchy of the human body is the organism level. This level encompasses all the systems and structures that function together to sustain life. At this level, the human body operates as a complete entity, integrating various organ systems such as the circulatory, respiratory, and nervous systems to maintain homeostasis and support overall health.
The levels of organization in the living world are: atoms, molecules, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, and biosphere. These levels represent a hierarchy of complexity, with each level building upon the one before it to create a functional living organism.
From least to greatest: Molecule, Cell, Organelle, Tissue, Organ, Organ System, Population, Community, Ecosystem, and Biosphere
the hierarchy of cells from cells onward is :cells, tissues(this is the ensemble of cells), organ, organ system, organism.

The Organ Level
Levels of organization are the way Biology is layered in a hierarchy. For example, organs make up one level, as the fourth level of organization.
Chemical Level(atoms, molecules), Cellular Level(smooth muscle cell), Tissue Level(smooth muscle tissue), Organ Level(stomach), System Level(digestive system), and Organism Level.
The highest level in the organizational hierarchy of the human body is the organism level. This level encompasses all the systems and structures that function together to sustain life. At this level, the human body operates as a complete entity, integrating various organ systems such as the circulatory, respiratory, and nervous systems to maintain homeostasis and support overall health.
The level of human organizational hierarchy that is above the cellular level is the tissue level. Tissues are groups of similar cells that work together to perform specific functions. In humans, there are four primary types of tissues: epithelial, connective, muscle, and nervous tissues. These tissues combine to form organs, which further organize into organ systems.

Segmental level
the hierarchy of cells from cells onward is :cells, tissues(this is the ensemble of cells), organ, organ system, organism.
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.
