Which outcome results if the original gravity-fed system for a Mughal garden fountain lacks maintenance?

💡 Explanation

Algae growth obstructs water flow, because the lack of filtration/cleaning in the gravity-fed system leads to increased organic matter encouraging biological fouling via biofilm build-up. Therefore, the algae clogs pipes, rather than causing structural damage; only biological matter concentrates.
