(a) According to ecologists, tropical regions in the world account for greater biological diversity. Justify.
(b) Why are habitat loss and alien species invasion considered as the causes of biodiversity loss ? Explain with the help of an example of each.
a)
According to ecologists, tropical regions in the world account for greater biological diversity. As the tropical environment is less seasonal, more constant and it is predictable, so this type of constant environment promotes niche specialization. Even in tropical regions, more solar energy is available in the contributes to higher productivity and greater diversity.
