I was trying to help answer this question to the best of my ability and I did some research and found a website with the link that might be helpful... I had originally posted the information that I thought might be relevant however, It was flagged for plagiarism which was not my intention at all!! I gathered some more information and re-wrote it. I'm not sure I explain quite as well as the original source. "8 Levels of Organization" By: Amanda Soderlind but I gave it my best try!
8 levels of living things largest to smallest
1. Organism- Is a singular living article that shows properties of life
2. Organ system- is a group of multiple organs that work together
3. Organ- a part of an organism that is typically self-contained and has a specific vital function. It is made of two or more tissues that work together for a common function
4. Tissue- All living things are made up of cells. Cells are the smallest unit of living things.
• Tissue is a cellular departmental level between cells and complete organs. A tissue is a group of similar cells and their extracellular matrix from the same origin that together carry out a specific function. (Organs then form by the functional grouping together of numerous tissues)
5. Cells- Cells are the basic structures of all living organisms.
6. Organelle- is a very small cellular structure that performs specific functions within a cell
7. Molecule- is a particle made up of two or more atoms that are chemically bonded together
8. Atom: Are the basic units of matter for example- The element of helium
