What is the correct sequence of biological components in order of decomposition?

The correct sequence of biological components in order of decomposition is cells, tissues, and then organs. This order reflects the hierarchical organization of biological structures in living organisms.

Cells are the smallest units of life and represent the basic building blocks of all living organisms. After the death of an organism, the process of decomposition begins at the cellular level. Individual cells break down as enzymes and microorganisms work to break down cellular components.

Following the breakdown of cells, tissues—which are groups of similar cells working together—begin to decompose. Tissues consist of networks of cells that perform a specific function. As the tissues decompose, they lose their structural integrity and functionality.

Finally, organs, which are made up of different types of tissues working harmoniously for specific functions, decompose. Organs are larger structures and therefore take longer to break down compared to the microscopic cells and tissues. Thus, the sequence reflecting the order of decomposition aligns with the biological structure hierarchy, where cells decompose first, followed by tissues, and finally, the organs.
