Give geographical reasons

A wide variety of species of insects is found in Brazil.

A wide variety of insects is found in Brazil because it has a high diversity and density of wildlife in the Amazon rainforests. Evergreen forests are found in this region around the Amazon basin as it rains throughout the year. Because of the deposition of sediments brought up by the river amazon and as the amazon canal is 150km in width, it forms ideal conditions in terms of soil and water for the growth of dense forests. Apart from the numerous species found in the tropical rainforests of north, they are also found in the swamps, grasslands, deciduous forests etc.
