A cell is much smaller than an organ. Organs are made up of many cells and tissues.
A cell is a building block that makes up an organism, so yes a cell is smaller than an organism, but you can also get single celled organisms such as some algaes
Organelle
To answer this question as it is written: not necessarily. An organism (bacterium) can be smaller than tissue (the cartilage in my ears). By definition, an organism is more COMPLEX than a tissue, but not necessarily bigger.
An organ can be part of more than one organism. Also I like ninja monkeys.
The level of organization more complex than a system is the organism. The organism is made up of multiple organ systems working together.
an organism because an organism can contain multiple organ systems
Not necessarily. Organs are not always bigger than tissues, they are just more complex. An organ can be as small as a lymph node, but a tissue may be as big as a muscle. So, the more complex it is, being made of more than one type of tissue classifies it as an organ, whereas the similarity of all the cells being the same categorizes it as a tissue. Organs are things like hearts, lung, livers, etc. Tissues are small/tiny pieces of animal or plants containing similar cells.

No
organ is bigger
That is the highest level. It goes: similar cells form a tissue, tissues form an organ, various organs form an organ system and many organ systems form an organism.
It is organ, not an organism.
