One important way fungi are different is the way they eat. Plants make their own food, using chlorophyll, sunlight, water, and carbon dioxide. Fungi cannot make their own food because they do not have chlorophyll. They must eat other living or once-living matter. Animals eat other living or once-living things too, but fungi are not the same as animals, either. Fungi do eat other living or once-living things, but they do not have stomachs. Fungi live in their food. They absorb it with their surfaces, and when they need more food, they just grow out further to touch more food. Some fungi get their food from things that once were alive, such as dead trees. They help to break down dead things into soil. Organisms which break down dead matter are called decomposers. Other fungi get their food by growing on other living things. If an organism lives on and harms another living thing, we call it a parasite. The organism a parasite lives on is called a host. http://www.dmturner.org/Teacher/Library/5thText/SimplePart2.html Most fungi are saprophytic deriving nutrition from dead matter (organic compounds). A few are parasitic; parasites requiring living hosts. All fungi require an external source for organic material. To obtain food, they extrude digestive enzymes and other substances which break down complex external nutrients. Fungi then absorb the nutrients by "bathing" in the mixture of their secretions and moisture from the environment. Moisture is vital for fungi precisely because they must bathe in their nutrients to absorb them. Although fungi also need oxygen, removing moisture is the most effective method for halting growth. http://www.aquarestoration.com/fungi_eat.asp

My favourite fungi, if one can make claim to a favourite, are the various strains of yeast used in wine- and beer-making. Yeast is classified as a fungus because it contains no chlorophyll and cannot manufacture its own food supply from carbon dioxide and water, as do green plants. Only a few strains of yeast can induce alcoholic fermentation. These yeasts consume sugars and excrete carbon dioxide and alcohol. Fermentation begins with an aerobic stage that produces little alcohol, followed by an anaerobic phase in which most of the alcohol is produced. C6H12O6 + yeast = 2xCH3CH2OH + 2xCO2 Some yeasts are used for baking. Bread rises because the baker's yeast excretes carbon dioxide, which forms bubbles in the dough and causes its volume to expand.

Fungi are able to use a huge variety of substances for food. We've all seen them growing on anything from bread and other foods to bathroom tiles, concrete surfaces, live organisms such as plants and even our own skin and within such organs as our lungs! On the molecular level, fungi simply need substrates that provide them with a source of nitrogen and carbon. In the laboratory, we can easily culture fungi in a solution of glucose (as the carbon source) plus something like ammonia (as the nitrogen source). The carbon and nitrogen sources can be swapped with many other substances like charcoal for carbon and certain amino acids for nitrogen. So essentially, there's no stopping fungi from consuming almost anything they come in contact with.

I really do not kno what fungi eat but i think they eat dead organisms.

i dunno lah! so lame lor! i don't care of wadever fungi or wadever!!or inoe! may be eat lei xue mei! hahaha! lei xue mei. stupid freaking lei xue mei! she is a bitchy bitch! muhhahahaha
