Why does the agouti need the Brazil nut tree?
They eat several nuts and also hide some for later ~ these are sometimes forgotten and go on to become new trees. Thus, the agouti plays an essential part in seed dispersal and regeneration in the Brazil nut tree’s lifecyle.
Which animal eats Brazil nuts?

Euglossine bees
Euglossine bees (most often the females) are the only creatures regularly able to gain entrance to the Brazil nut tree’s flowers, which have lids on them.

Do Brazil nut trees have deep roots?
One surprising trait of the Brazil Nut tree is its absorption from the soil, of not only barium, but also the chemically related radioactive element radium.
