Theory:

Habitats located in the land area are called terrestrial habitats.
The land area that makes up around 28% of the world belongs to terrestrial habitat.
This includes natural habitats like forests, grass lands and man made habitats like farm lands and urban environment like towns and cities.
 
Terrestrial habitats are classified as:
  • Desert habitat
  • Grassland habitat
  • Forest habitat
Desert habitat
  
Habitats that exist in deserts belong to this category. These habitats are dry, receive scanty rainfall (less than 25cm/yr.).

The plants in this habitat developed special characteristics to overcome excessive heat and very little water availability.
 
The following are some of the characters desert plants exhibit:
  • Thick leaves - to store water and minerals.
  • Spines - some plants convert their leaves to spines to overcome water loss through evapotranspiration.
  • Long roots - to penetrate the land and reach the ground water source.
  • Thar desert is the desert habitat we have in India. Which is located in the state of Rajasthan.
  • These habitats receive scanty rainfall less than 25 cm annually.
Grassland habitat
  
This habitat is characterized by the vast area of grasses. The grasses grow up to a height of 2 meters. For example, Savanna grassland.

Forest habitat
 

This habitat is characterized by the presence of forest area mostly dominated by trees.
  • Forests found in tropical area are called tropical forest.
  • Forests in temperate zone has temperate forest and forests found in mountains are called mountain forests.
The rainfall ranges from 25-200 cm in forest habitats.
