Place living organisms in order from structurally advance to more simple. [Paramecium (protists), tree (plant), mouse (animal), E. coli (bacteria),
Order- Structurally advance to more simple
Most structurally advanced - mouse, tree, paramecium, and E.coli (most simple)
Animals are the most structurally advanced organisms as they have developed various systems to perform the division of labor. for example, Mouse has evolved forelimbs and hind limbs for movements that enable the mouse to search for food and protect itself from predators.
Plants come in second as they have a dense network of roots, branches and leaves which enable the tree to communicate with the surrounding. Trees don't have limbs to move, they are immobile but their roots can extend to great areas for accessing water.
Paramecium is unicellular eukaryote which contains all the cell organelle important for independent survival of the cell. paramecium move from one place to another with the help of cilia, which are fingerlike projections on the cell.
Last is E.coli. It is a prokaryotic bacteria. One of the most primitive organisms. Just like paramecium, E.coli also contains organelles needed for its independent survival but there are several differences between E.coli and paramecium like genetic material is present in the double-membrane bound nucleus in paramecium whereas in E.coli the genetic material lies naked in the form of the nucleoid.
