Fungi are heterotrophic organisms, meaning they obtain their nutrients from organic sources. There are three main types of fungal metabolism:
1. Saprophytic metabolism: Saprophytic fungi obtain their nutrients by decomposing dead organic matter. They secrete enzymes that break down complex organic molecules into simpler compounds, which can then be absorbed by the fungus. This process is essential for recycling nutrients in ecosystems and plays a crucial role in the decomposition of organic matter.
2. Parasitic metabolism: Parasitic fungi obtain their nutrients from living organisms, often causing harm or disease to their host. These fungi typically penetrate the host's tissues and absorb nutrients directly from the host's cells. Some parasitic fungi can cause serious diseases in plants, animals, and humans.
3. Symbiotic metabolism: Symbiotic fungi form mutually beneficial relationships with other organisms. One of the most well-known examples of symbiotic fungi is mycorrhizae, which form associations with plant roots. The fungi provide the plant with nutrients such as phosphorus and nitrogen, while the plant provides the fungus with sugars produced through photosynthesis. This symbiotic relationship is essential for the health and growth of many plant species.
Overall, fungal metabolism plays a crucial role in nutrient cycling, decomposition, and ecosystem functioning. The diverse metabolic strategies of fungi allow them to thrive in a wide range of environments and interact with a variety of organisms.

1. Saprobic Metabolism:
- Fungi obtain nutrients by decomposing organic matter, such as dead plants and animals.
- They secrete enzymes to break down complex compounds into simpler substances.
- Examples include mushrooms and molds growing on decaying logs or fruit.
2. Parasitic Metabolism:
- Fungi obtain nutrients from living hosts, causing them harm or disease.
- They often penetrate the host's tissues and absorb nutrients directly or release toxic substances.
- Examples include rust fungi on plants and Candida infections in humans.
3. Symbiotic Metabolism:
- Fungi form mutually beneficial relationships with other organisms.
- Mycorrhizae: Fungi form associations with plant roots, enhancing their nutrient uptake in exchange for carbohydrates.
- Lichens: Fungi form a symbiotic relationship with algae or cyanobacteria, providing shelter and moisture while receiving photosynthetic products.
4. Autotrophic Metabolism:
- Some fungi can synthesize their own food from inorganic compounds, similar to plants.
- Photosynthetic fungi contain chlorophyll a and other pigments to capture sunlight.
- Examples include Trechispora hyaline and Glaucocystum keukensii.
5. Aerobic Metabolism:
- Fungi require oxygen for their metabolic processes.
- They utilize oxygen to break down glucose through glycolysis, the Krebs cycle, and oxidative phosphorylation.
6. Anaerobic Metabolism:
- Some fungi can survive and grow in the absence of oxygen.
- They undergo fermentation or anaerobic respiration to obtain energy from glucose.
- Examples include yeasts and rumen fungi.
7. Heteroauxotrophic Metabolism:
- Fungi require specific organic compounds for growth, such as vitamins or amino acids.
- They cannot synthesize these compounds on their own and must obtain them from their environment.
8. Autoauxotrophic Metabolism:
- Fungi can synthesize all the essential organic compounds they need for growth.
- They are independent of external sources of specific nutrients.
- Fungi obtain nutrients by decomposing organic matter, such as dead plants and animals.
- They secrete enzymes to break down complex compounds into simpler substances.
- Examples include mushrooms and molds growing on decaying logs or fruit.
