est and simplest is the cellular level. Organisms here are either unicellular organisms, like protozoa, or colonial organisms. Colonial organisms are composed of single-celled individuals that stay together to sustain the life of the whole colony. Next on the scale of complexity is the level occupied by tissue. A tissue is a group of similar cells which perform a similar activity. Tissues that are organized around a common function together make up an organ, the third level of complexity. The fourth level of organization is the system, formed by a group of organs which together perform a specific bodily process. The fifth and highest level is the organism level, in which body systems work together in a structure capable of independent life. main idea:
