B. The levels of classification increased. Previously there were only 2 domains of life, Bacteria and Eukarya, but an additional domain and Kingdom were added when the distinction of Archaea was observed.
This might refer to the phosphorus cycle.
Phosphorus cycle is a biogeochemical cycle that observes how phosphorus move through minerals, soil, water, and organisms. Typically, plants absorb phosphorus from the soil. And animals get phosphorus from the eaten plants. When these organisms dies, they decay and the phosphorus returns to the soil and inorganic matter.
If the mutation is beneficial, the mutated organism survives to reproduce, and the mutation gets passed on to its offspring. In this way, natural selection guides the evolutionary process to incorporate only the good mutations into the species, and expunge the bad mutations.
