Anuta_ua [19.1K]

Answer:

The reason that there is no fruit even the plant produced healthy flowers maybe because

1. absences of pollinators due to declining poliinator population

2.weather conditions are preventing pollination

3. prevalence of flooding

Explanation:

1.Fruits are direct result of pollination. Due to the decrease in the number of pollinators especially orchid bees, some fruit bearing plants produce flowers but no fruit.

Bees decline their population because of parasites, diseases, exposure to chemicals and other environmental factors.

2.Unfavorable factors may prevent the agents of pollination to do their jobs. Bees and other insects may be hindered by wet or cold weather or some use of chemicals.

3.Brazil nut grow in lowland rainforest where there is no flooding.
