Usually, complex organisms consist of many organ systems, which comprise from two or more organs, which is from two or more tissues, which comes from two or more cells working for the common function.
This was a waste of my time

Simple Organism some simple organisms are made of single cell. Others are made of many cells that are similar Complex organisms in complex organisms, cells are organized into tissues, which make up organs. Organs form organ systems.
Complex organisms need cells that perform many different functions. Complex organisms are capable of a lot of different things, and that variety needs to be supported on the cellular level. Without them, complex organisms cannot perform different functions.
The complexity of body design will increase over evolutionary time. This is the process by which new modifications occur in the organisms. So, in this way we can say that advanced organisms will be complex as compared to complex organisms...

advantages of human beings are complex organisms

From smallest to largest, a multicellular organism can be organized into cells, tissues, organ systems, and organisms.
Cells are organized into tissues, which are organized into, organs, followed by organ systems and finally organisms.

Cells are organized into tissues in multicellular organisms. Tissues are further organized into organs. This organization allows for the localization and isolation of biological processes.
