What is the correct order of the hierarchy of biological organization from simplest to most complex?

Species, Organism, Cells, Tissues
Cells, Tissues, Organism, Species
Tissues, Cells, Organism, Species
Species, Organism, Tissues, Cells

The correct answer is: Species, Organism, Tissues, Cells

The hierarchy of biological organization starts with the simplest unit, which is the cell. Cells make up tissues, and tissues make up organs which in turn make up organ systems. Organ systems work together to form an organism, which is a single living individual. A group of similar organisms forms a species. Option A is incorrect because the order is reversed. Option B is incorrect because the order of cells and tissues is reversed. Option C is incorrect because tissues cannot come before cells in the hierarchy. The correct order, as mentioned above, is from simplest to most complex Cells, Tissues, Organs, Organ Systems, Organisms, Species. Therefore, the correct answer is D.
