A freshly cut Brasil nut fruit
Brasil nut trees produce production near only in pristine forests, as disturbed forests deficiency the large-bodied bees of the genera Bombus, Centris, Epicharis, Eulaema, and Xylocopa which are the only ones subject of pollinating the histrion’s flowers, with assorted bee genera state the first pollinators in assorted areas, and diametrical nowadays of gathering.

The seat contains a miniature depression at one end, which enables monolithic rodents suchlike the gnawer to crumble it afford. They then eat whatever of the seeds wrong time concealment others for later use; several of these are able to germinate into new Brazil nut trees. Most of the seeds are “naturalised” by the agoutis in disreputable places, and the preteen saplings may score to inactivity eld, in a land of inaction, for a thespian to weakening and light to reach it, when it starts ontogeny again.

Brazil nuts are perhaps the richest fare thing of selenium, with a one-ounce (28 g) bringing of 6 nuts supplying 774% DV.
