Fungi that absorb soluble organic matter from dead substrates are called saprophytes. They are heterotrophic organisms that release enzymes to digest dead organic material externally, playing a critical role in decomposition and nutrient cycling.

• Saprophytes: Organisms that get nourishment from dead and decaying matter.

• Parasites: Derive nutrition from living organisms.

• Lichens: Symbiotic associations between fungi and algae
