The fungus Pilobolus , a mucoromycete, exhibits a unique spore dispersal strategy. What is the most significant ecological advantage of Pilobolus launching its sporangia towards light and onto fresh grass, followed by animal ingestion?

  • A: It ensures the spores land on moist food, preventing desiccation.
  • B: It allows for the rapid decomposition of animal dung directly underneath the fungus.
  • C: It facilitates long-distance dispersal of spores to new substrates via grazing animals, enabling colonization of new environments.
  • D: It primarily attracts other fungi to form symbiotic relationships.

Explanation

The text explains that Pilobolus launches its sporangia onto fresh grass, where they are ingested by grazing animals. These animals then scatter the spores in their feces, enabling the growth of the next generation of fungi in new locations. This describes an effective long-distance dispersal strategy.
