A living cell is b living organism because basically the word living cell says it all
Cyracolution
If tyou are speaking from an evolutionary point of view, the simplest 'complex living organism' would be an Amoeba. They are single celled organisms but carry out all the functions an organism does with that single simple but effective cell structure. However from a chemistry point of view, inside a single cell are Proteins, and they are constructed from Amino Acids. Any smaller than that and you are just talking about individual atoms so Amino Acids are often regarded as the building blocks of living organisms.
Simplest to More Complex. 1. Cells 2. Tissue 3. Organ 4. Organ system 5. Organism
Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of themselves. Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell.
any living thingAn organism is a living plant or animal.
d) all

A complex structural organization is an essential characteristic of a living organism
carbon
Yeast is a living organism much like a mold.
No. The least complex level of organization in living things is atoms and molecules.
The cell.
they break up the food

An "Atom" is the basic building block of all molecules [first] and [then] biomolecules.
an organism is any living thing...plant or animal, single celled living things etc...an animal is an organism that is differentiated from plants in that can move and have a more complex nervous system ie brain, spinal cord etc
The building blocks of a plant are more likely to be the same as any other living organism, DNA.
