      Lesson details

      Learning outcome

      You can describe how Brazil nuts are grown, harvested, and exported, and threats to their production and trade.

      Key learning points

      1. Brazil nuts have a specific life cycle, to which there are some potential threats.
      2. Agouti are small rainforest animals which are critical for the life cycle of Brazil nuts in the rainforest ecosystem.
      3. The plants and animals in the rainforest are interconnected and depend on each other.
      4. A variety of information sources can be used to investigate Brazil nuts and threats to their production and trade.

      Keywords

      • Pollinate - Pollinate means depositing pollen on parts of a plant or flower to enable fertilisation to take place.

      • Life cycle - A life cycle is the series of stages that plants, animals and other livings things go through during their lifetime.

      Common misconception

      Pupils think that Brazil nuts are only found in Brazil.

      Brazil nuts can be found in multiple countries in South America including Peru, Brazil, Ecuador and Colombia.

      Teacher tip

      As an additional activity, pupils could investigate an example of interdependence in the UK.

      Q3.
      Order these stages of the Brazil nut lifecycle.

      1 - the Brazil nut tree flowers for only a single day each year
      2 - the flowers of the Brazil nut tree are pollinated by the Euglossine bee
      3 - the flowers of the Brazil nut tree slowly develop into fruit (pods)
      4 - the Brazil nuts fall to the ground and are eaten by the agouti
      5 - the agoutis spread any uneaten nuts (the tree’s seeds) in the rainforest
      6 - some of these seeds grow into Brazil nut trees

      Q4.
