Question

Give Reasons: 1. Each forest type corresponds with a particular species of wildlife. 2. As the rainfall decreases, size and density of vegetation decreases.

Answer 1

1ST ANSWER:
Each forest type corresponds with a particular a species of wildlife since animals native to particular areas are naturally adapted to that kind of environs. For example, animals like the arctic fox and arctic hare are found in Taiga (northern coniferous forest) and are adjusted to cold conditions there. These animals would not be found in tropical forests, as they cannot adapt to such climatic conditions.

2ND ANSWER.
 ​​​​​​Vegetation of a particular region is influenced by several factors including rainfall. Regions of high rainfall and fertile soils have lush, dense forest since abundant supply of water makes the same possible. The vegetation show marked difference in the regions of moderate or scanty rainfall. Regions of moderate rainfall have short stunted trees and grasses whereas regions of scanty rainfall like that in deserts give way to only thorny shrubs and scrubs since it is not possible for dense forests to thrive with such little rainfall.
