Fungi are important decomposers in terrestrial ecosystems. Some fungi are able to break down lignin in plants, through the production of an enzyme called lignin peroxidase, something that no other organism can do. The ability to break down lignin by some fungi is reflected by which of the statements? A. Expression of genes necessary to break down lignin were lost in lineages that are not in the evolutionary history of fungi.
B. A mutation occurred in a gene found in some fungi, and the enzyme produced is able to break down lignin.
C. Many organisms have the end to producentymes for breaking down lignin but do not express those genes
