16.) If economics was biology, macroeconomics would be ecology, while microeconomics would be __ plant science geology cell biology

## Step 1<br />The problem is a metaphorical comparison between the field of economics and the field of biology. The question asks us to identify the equivalent of microeconomics in biology.<br /><br />## Step 2<br />In biology, ecology is the study of the interactions between organisms and their environment, which is a broad perspective. This is similar to macroeconomics, which studies the economy as a whole, including the interactions between different sectors and the overall economic environment.<br /><br />## Step 3<br />On the other hand, cell biology is the study of individual cells and their functions, which is a more specific and detailed perspective. This is similar to microeconomics, which focuses on individual economic units such as households and firms, and their interactions.<br /><br />## Step 4<br />Therefore, in the context of biology, microeconomics would be equivalent to cell biology.
