Designed with EdrawMax, this template is a classification diagram for multicellular organisms. It begins by dividing multicellular organisms based on two main characteristics: photosynthesis and heterotrophy. Organisms with a cellulose cell wall and involved in photosynthesis are further categorized as marine, leading to species like Halymenia muelleri. Heterotrophic organisms with bilateral symmetry and segmentation are shown with a chitinous exoskeleton, branching into soil - dwelling species such as Sculigereila echinostylus. Other branches are based on features like the number of wings and specific ecological behaviors of insects. This diagram serves as a useful tool for understanding the taxonomic and evolutionary relationships among multicellular organisms in the biological field.
