As a mycologist, I specialize in the study of fungi, a diverse group of organisms that play a crucial role in ecosystems around the world. Fungi are indeed heterotrophic, meaning they cannot produce their own food through photosynthesis like plants. Instead, they obtain their nutrients by absorbing them from the environment. This absorption can occur in various ways, and it's important to note that not all fungi feed exclusively on dead organic matter, as is commonly believed.
Fungi have a unique relationship with their environment. Some fungi are saprophytic, meaning they decompose dead organic material and recycle nutrients back into the ecosystem. This is a critical process for nutrient cycling in many ecosystems. However, other fungi are parasitic, which means they can derive their nutrients from living organisms. This can include plants, animals, and even other fungi.
The parasitic relationship can be direct, where the fungus invades the host's tissues and extracts nutrients, often causing disease or harm to the host. For example, the fungus that causes athlete's foot, Trichophyton, is a parasitic fungus that feeds on the keratin in human skin. Another example is the fungus that causes Dutch elm disease, which infects and kills elm trees.
On the other hand, some fungi have a mutualistic relationship with living organisms. Mycorrhizal fungi, for instance, form a symbiotic relationship with the roots of most plant species. These fungi extend their hyphae into the soil, increasing the surface area for nutrient absorption, and in return, the plant provides the fungus with carbohydrates produced through photosynthesis.
It's also worth noting that some fungi are capable of switching between different modes of nutrition. Depending on the environmental conditions and availability of nutrients, a fungus may act as a decomposer, a parasite, or engage in a mutualistic relationship.
The nutrients absorbed by fungi are indeed made available to other organisms in the ecosystem. When fungi are consumed by other organisms, such as when a deer eats mushrooms or when a beetle larva feeds on decaying wood, the nutrients stored in the fungal tissues are transferred to the consumer. This makes fungi an important link in the food chain, connecting the dead organic matter to the consumers that rely on them for sustenance.
In conclusion, while the common perception may be that fungi only feed on dead organic matter, the reality is much more complex. Fungi, through their diverse modes of nutrition, can indeed feed on living organisms, either as parasites or in mutualistic relationships, and play a vital role in the flow of nutrients within ecosystems.

Fungi are heterotrophic. Fungi are not able to ingest their food like animals do, nor can they manufacture their own food the way plants do. Instead, fungi feed by absorption of nutrients from the environment around them. ... Nutrients absorbed by the fungus then become available for other organisms which may eat fungi.
