Q

the Brazil nut tree, the agouti, the female euglossine bee and the gongora orchid plant are ‘linked’ because:

A
  • the agouti is the only animal able to open the Brazil nut’s pod of fruit, so is the only one able to spread its seeds
  • the female euglossine bee is the only pollinator which fertilises its flowers
  • the male euglossine bee relies on the gongora orchid to attract females

-in this way, a decline in any of these populations will affect the others
