The fungi which grow on dung is called as a. Epixylicb. Coprophilousc. Keratinophilicd. Xylophilous

The correct answer is b. Coprophilous.
Coprophilous fungi are those that grow on dung (animal feces). These fungi play an important role in breaking down and decomposing organic matter, especially the dung from herbivores. They are adapted to thrive in the nutrient-rich environment provided by animal waste.
Characteristics of Coprophilous Fungi:
• These fungi are typically found on the dung of herbivores such as cows, horses, and rabbits, but can also grow on the dung of omnivores and carnivores.
• Some examples of coprophilous fungi include species in the genera Pilobolus, Agaricus, and Coprinus. These fungi often have specialized mechanisms for dispersing their spores, which helps them colonize new areas where dung is present.
Why the Other Options Are Incorrect:
1. a. Epixylic: Epixylic fungi grow on dead wood (xylem) or decaying plant material, not on dung.
2. c. Keratinophilic: Keratinophilic fungi thrive on keratin, a tough protein found in hair, nails, feathers, and skin. They are not associated with dung.
3. d. Xylophilous: Xylophilous fungi grow on wood (xylem), not on dung.
The fungi that grow on dung are called coprophilous fungi, so the correct answer is b. Coprophilous.
