All fungi are always

All fungi are always heterotrophs. They lack the ability to produce their own organic compounds through photosynthesis. Instead, they obtain nutrients by absorbing preformed organic matter from their environment. While some fungi are parasitic, obtaining nutrients from living organisms, others are saprophytes, decomposing dead organic matter. Regardless of their lifestyle, fungi depend on external sources of organic carbon for energy and growth. This reliance on external nutrients distinguishes them from autotrophs, which can synthesize their own organic compounds using inorganic sources such as carbon dioxide and water. As heterotrophs, fungi play crucial roles in ecosystems by participating in nutrient cycling and decomposition processes, breaking down complex organic matter into simpler compounds that can be recycled and utilized by other organisms. This metabolic strategy enables fungi to thrive in diverse habitats and contribute to the balance of ecosystems worldwide.
