Final answer:
An amoeba's advantage over a lizard's cell is its ability to independently perform all life processes, opposed to the lizard cell's requirement for a complex body system.
Step-by-step explanation:
One advantage an amoeba has over a cell of a lizard, in relation to their levels of organization, is its autonomy and self-sufficiency. An amoeba, being a single-celled organism, can carry out all necessary life processes independently. It can move, feed, respire, and reproduce without the need for other cells or a complex body system. In contrast, a cell within a lizard is highly specialized and requires the support and integration of other cells and systems within the organism to function. Additionally, amoeba can exhibit forms of cellular simple organization such as forming biofilms or aggregations like slime molds, which provide some benefits similar to multicellularity without losing their capability to survive independently.
