Explanation: 

Detailed explanation-1: -Drupe has a fleshy pericarp, or ovary covering, which surrounds a single seed encased in a stony endocarp, e.g., a peach, prune, cherry, olives, or coconut. A local example would be Prunus ilicifolia or holly-leaf cherry. Aggregate has several drupe-like individual fruits coming out of th same receptacle.

Detailed explanation-2: -Examples include mangoes, guavas, breadfruit, carob, and several fig species. In South Africa a desert melon (Cucumis humifructus) participates in a symbiotic relationship with aardvarks-the animals eat the fruit for its water content and bury their own dung, which contains the seeds, near their burrows.

Detailed explanation-3: -Since the fruits are also fleshy, groundcherry seeds can potentially be dispersed in three ways: ingestion, water, and wind.
