What term describes organisms that are not particularly specialized and are simple in structure?

The term that describes organisms that are not particularly specialized and are simple in structure is "Simple Organisms." These organisms typically have a basic level of organization and fewer specialized structures and functions compared to more complex organisms. They often belong to the categories of unicellular organisms, such as bacteria and some protists, or very simple multicellular organisms, such as sponges. Their simplicity allows for essential biological processes to occur without the need for intricate systems or structures found in more complex life forms. This straightforward organization means that simple organisms can efficiently carry out basic life functions with minimal specialization, which often makes them adaptable to a variety of environments.
