LIFE SCIENCE

Detailed explanation-1: -Many organ systems are then organised and form an organism. So, the correct order is: Cells-Tissues-Organs-Organ systems-Organism.

Detailed explanation-2: -The major levels of organization in the body, from the simplest to the most complex are: atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism.

Detailed explanation-3: -Typical levels of organization that one finds in the literature include the atomic, molecular, cellular, tissue, organ, organismal, group, population, community, ecosystem, landscape, and biosphere levels.

Detailed explanation-4: -An organism is made up of four levels of organization: cells, tissues, organs, and organ systems. These levels reduce complex anatomical structures into groups; this organization makes the components easier to understand.

Detailed explanation-5: -The human body has many levels of structural organization. The simplest level is the chemical level, which includes tiny building blocks such as atoms. Cells are the smallest functional units of life.
