Question

forests are biodiversity hot spot justify this statement

Answer 1

Biodiversity hotspot is related to species extinction. It can be defined as region where critical level of biodiversity or wildlife has been depleted critically.  

Regions are classified as biodiversity hotspot based on
- 0.5% of the total vegetations/plants must be endemics (on the brick of extinction) 
- 80% of original plantation or trees of the region must be lost

Now, consider forest. For example, Western ghat of India (Sahyadri) or Amazon forest. These forest (along with many other forest throughout the world) have been destroyed more than 70% and 0.5% of the plants are endemic - meaning these forests satisfy both must conditions. 

For this reasons, these two and other forests in the world are considered as "Biodiversity Hotspot".

Answer 2

Forests are rightly biodiversity hot spot due to the presence of a large number of species in these forests. There are a large number of species of plans, animals, birds, insects and herbs in a forest habitat.
Forests provide shelter, habitat and food to these species making long food chains and webs. That's why plants, animals, insects, birds and herbs species rapidly flourishe in these forests.
