Life processes of the human body are maintained at several levels of structural organization. Cells can be prokaryotic (without nucleus) or eukaroyotic (with nucleus). Under certain physiological conditions, the fibers in turn distort the shape of red blood cells (cell level), so that the cells become curved and twisted. At the next level of ecological organization lies the ecosystem, a biological environment comprising all the living organisms and non-living things (or abiotic factors such as air, soil, and water) in a particular region and the interaction between them.Though many people refer to these levels as the levels of organization in an ecosystem, it is technically incorrect as ecosystem in itself . In this section I will explain how two of the body systems interrelate to perform a function. B. order All living things are made of cells; the cell itself is the smallest fundamental unit of structure and function in living organisms. As more is learned about organisms, the taxonomy changes.
