A. Multicellular
B. Unicellular
C. Abiotic
D. Biotic



Answer :

Final answer:

Multicellular and unicellular organisms differ in their levels of organization and functional independence.


Explanation:

Multicellular organisms are those that can contain up to five levels of organization, including cells, tissues, organs, organ systems, and the organism level itself. These organisms, such as humans, have specialized cells working together for the functions necessary for life.

On the other hand, unicellular organisms are single-celled and can function independently, without the need for different levels of organization like those found in multicellular organisms.

Understanding the levels of organization in living beings is crucial in biology to comprehend how different organisms operate and maintain life functions.
