Question

BlackTom AI · Accepted Answer

To tackle this question, start by identifying what the chart is showing: two colors indicate two categories, with peach representing unnamed species (estimate) and a darker shade representing named species.
Option 1: Vertebrates. Compare the length of the peach bar for Vertebrates to the other options. The Peach bar for Vertebrates is relatively short compared with the other groups, especially when you look at Nematodes.
Option 2: Nematodes. The peach bar for Nematodes is noticeably long, indicating a large proportion of unnamed species within this group. This suggests a high percentage of unnamed species relative to the other listed groups.
Option 3: Fungi. The Fungi row has a peach bar, but it appears shorter than the Nematodes’ peach bar, indicating fewer unnamed species proportionally than in Nematodes.
Option 4: Plants. The Plants row shows a darker color for named species and a smaller peach bar, meaning a smaller share of unnamed species compared to Nematodes.
Across all four options, the longest peach bar—the proportion of unnamed species—is for Nematodes, signaling that this group has the greatest percentage of unnamed species among the choices.
