Summary Introduction

To contrast: The nutritional mode of fungus and humans.

Concept introduction: Nutrients are the substances in food that maintain the body and make it work. Fungi are multicellular eukaryotes (except yeast) and are classified according to their structure and mode of reproduction. Fungi are achlorophylous (do not contain chlorophyll and not able to make food). They are heterotrophic feeders as they depend on other organisms for the carbon source. Unlike humans, they do not ingest their food but instead absorb nutrients from the surrounding environment by secreting various hydrolytic enzymes or act in the form of saprobes, symbionts, or parasites. By contrast, humans have the holozoic mode of nutrition; they relatively ingest large pieces of food and thus, digest the food in their bodies.
