How this line gives the answer

0, emb=1.0, combined=1.0). Verified: high — The span explicitly lists the estimated numbers for each organism group in the Amazon forest, allowing direct comparison to determine the descending order: invertebrates (>125,000) > plants (40,000) > fishes (3,000) > birds (1,300) > mammals (427), which matches option A.
