English: Baboon faeces, weathered, which exposes the seeds of a fruit that has very little flesh, but get passed in the faeces, a conspicuous example of zoochory. The berries are small and the seeds are large, so the baboons have to eat a large volume of them if they are to be nutritionally worth while. The weathering is largely the effect of soft matrix being washed from between the seeds by rain. Insects play very little part in this cycle because there is so little soft material between the hard seeds.
