Are Fungi Auto or Heterotrophic?
Answer – Fungi are heterotrophic organisms, or heterotrophs.
Explanation:
Based on their mode of nutrition, all living beings are grouped into two broad categories: autotrophs and heterotrophs.
Autotrophs synthesize their own food using inorganic substances in the presence of light (photosynthesis) or chemical energy (chemosynthesis). They convert sources like carbon dioxide and water into organic molecules that serve as food. Autotrophs are also known as producers and include plants, algae, and some bacteria.
Heterotrophs, on the other hand, cannot prepare their own food. They get their nourishment from organic matter that is either produced by plants or present in other living beings. Also called consumers, heterotrophs comprise all animals (herbivores, carnivores, omnivores), fungi, and several bacteria.
Fungi, specifically, obtain their food from the substrate through which they grow. Their filamentous hyphae secrete digestive enzymes that break down the substrate, allowing nutrients to be absorbed easily. Most fungi are also saprophytes, meaning they feed on dead or decaying organic material. Some are parasitic and feed on living organisms instead.
