In regions receiving rainfall between 1000 mm to 2000 mm in India, deciduous forests are found. There is o deciduous forest in Brazil.
b) Correlate wildlife and natural vegetation in India and Brazil.

Q 5. Give geographical reasons
a) The northern part of Brazil is covered by dense forests.
Ans)The northern part of Brazil is covered by dense forests because it is an equatorial region and receives rainfall throughout the year.
b) Vegetation is scarce in the high altitudes of Himalayas.
Ans) Vegetation is scarce in the high altitudes of Himalayas because of the cold weather. Maximum areas are covered by snow and experiences snowfall.At the highest altitude, seasonally flowering trees are found.
c) A wide variety of species of insects isfound in Brazil.
Ans) Evergreen forests, grasslands and swampy lands in Brazil are the main reason behind the growing species of the variety of insects. They get proper environment and ample of food over here.
d) Wildlife in India is decreasing day by day.
Ans) Wildlife in India is decreasing day by day because of poaching, pollution and rapidly occurring deforestation.
e) Like India, there is need of conservation of forests in Brazil too.
