The common building blocks of simple and complex organisms are called cells. They are the smallest structural unit of an organism.

They're both organisms, right?
Complex organisms evolved from simple organisms, so simple organisms evolved first.
Arthropods are complex organisms. They are made up of cells, tissues, organs, and organ systems.
My wife is complex. And she's an animal. But I don't think I'd call her an animal to her face...
Less complicating factors than trying to study complex organisms.

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.

A cell has the least complex organization, as it is the basic structural and functional unit of all living organisms. Cells are the building blocks of life and have a simple structure compared to organs, organisms, and populations.
Organisms are classified as simple if they only have one cell such as bacteria, and complex organisms have multiple cells that function together to keep the organism alive and maintai homeostasis.

Archaebacteria are some of the oldest organisms living on Earth. They are considered simple because of their external body structure.
cell is a building block of living organisms .
That depends on which organism. Generally, an organism is more complicated than an organ, but if the organism is unicellular (has one cell) then it could be more simple. Since one celled organisms don't have individual organs, then the anwer is that organisms are more complicated than organs.
Simple sugars are themselves building blocks of either complex sugars or carbohydrates. Glycol aldehyde is an example of a pre biotic simple sugar.
