Use the paragraph to answer the question.

Question

About 1.5 million species of fungi exist on Earth. They
act as nature’s decomposers. These
organisms break down matter and release enzymes and
acids that unlock nutrients for plants and soil organisms.
You may be familiar with macrofungi, a type of fungus
that includes mushrooms. But for the most part, fungi
exist as mycelia, tiny threads that snake underground in
billions of interconnected threads. They twist and twine
with tree root systems, helping tress obtain crucial
nutrients. Mycologists call these networks of mycelia
"Earth’s nervous system."
Which statement best identifies the central idea of the
paragraph?
