The image contains two pie charts labeled "a." and "b." comparing the proportions of different microbiota. **Pie Chart a.** - **Firmicutes**: occupies the largest section, about two-thirds of the chart. - **Other**: is the second-largest section, represented in blue. - **Bacteroidetes**: takes up a smaller segment, represented in red. **Pie Chart b.** - **Firmicutes**: again occupies the largest section, more than half of the chart. - **Bacteroidetes**: the second-largest section, larger than in chart a, represented in red. - **Other**: the smallest section, shown in blue. ### Biology: How Life Works © Macmillan Learning **Question:** Which of the two scenarios supports the hypothesis that microbiota in the son arrive by infection?

Nodules found on the roots of leguminous plants like soybeans harbor bacteria that fix nitrogen. These nodules are an example of the intimate and specialized partnerships that have been established over time between prokaryotes and eukaryotes. Coevolution maintains these types of relationships because both participants benefit. Plants receive biologically useful forms of nitrogen needed for growth, and the bacteria reside in an oxygen-free environment required by enzymes involved in the nitrogen-fixing process. Humans also maintain intimate associations with beneficial bacteria and even archaea. In fact, the prokaryotic cells in and on human bodies outnumber the eukaryotic human cells by tenfold, according to some estimates. These microbial inhabitants help humans digest food, provide essential vitamins absorbed by the intestines, and even impact the immune system. The microbes that coevolve with plants arrive by infection of root tissue. The microbiota that coevolve with humans colonize human tissues after birth. Consider the chart showing the distribution of the gut microbiota in a human female. The chart is a pie chart illustrating the distribution of different types of gut microbiota in a human female. It is divided into three main sections: Firmicutes (green), Bacteroidetes (red), and Other (blue). Panels (a) and (b) shown depict two scenarios for the distribution of the gut microbiota in her son. The son maintains a similar diet in both scenarios and has not undergone recent antibiotic treatment, which would decimate and/or alter the entire gut community.
