The Brazil Nut Tree, Bertholletia Excels (N = 17), Is

question 21

Multiple Choice

The Brazil nut tree, Bertholletia excels (n = 17) , is native to tropical rain forests of South America. It is a hardwood tree that can grow to over 50 metres tall, a source of high-quality timber, and a favourite nesting site for harpy eagles. As the rainy season ends, tough-walled fruits, each containing 8-25 seeds (Brazil nuts) , fall to the forest floor. Brazil nuts are composed primarily of endosperm. About $50 million worth of nuts are harvested each year. Scientists have discovered that the pale yellow flowers of Brazil nut trees cannot fertilise themselves and admit only female orchid bees as pollinators. The agouti (Dasyprocta spp.) , a cat-sized rodent, is the only animal with teeth strong enough to crack the hard wall of Brazil nut fruits. It typically eats some of the seeds, buries others, and leaves still others inside the fruit, which moisture can then enter and allow the remaining seeds to germinate.
-The same bees that pollinate the flowers of the Brazil nut trees also pollinate orchids, which are epiphytes (in other words, plants that grow on other plants) ; however, orchids cannot grow on Brazil nut trees. These observations explain ________.
