AP BIOLOGY

Detailed explanation-1: -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-2: -’Animals gulp down the fruits without chewing the seeds, digest the fleshy pulp and defecate the seeds. ‘ This ingestion process of dispersal is known as endozoochory.

Detailed explanation-3: -Animals disperse seeds by carryng them on their body or by eating the fruit of a plant and disposing the seeds at some other location as they move.

Detailed explanation-4: -These include beetles (e.g. weevils), bugs (e.g. seed bugs), wasps, ants, thrips and some moth species. In the process of feeding, seeds can be dispersed by simply knocking the seed from the plant to the ground or by being carried great distances from the plant. A few insects use seeds for other purposes.
