1. Tropical evergreen forests (or tropical rain forests) are usually found in areas receiving more than 200 cm of rainfall and having a monthly mean temperature of 18°C or higher in the coldest months. They occupy about seven per cent of the Earth’s land surface and harbour more than half of the planet’s terrestrial plants and animals. Tropical evergreen forests are dense, multi-layered, and harbour many types of plants and animals.
2. Tropical deciduous forest in India receives rainfall between 100 cm to 200 cm. Deciduous means "falling off at maturity" or "tending to fall off", and it is typically used in order to refer to trees or shrubs that lose their leaves seasonally (most commonly during autumn) and to the shedding of other plant structures such as petals after flowering or fruit when ripe.
3. Dry forests typically are found in very warm regions in the tropics, where the mean annual temperature is greater than 17ºC (63F), and where rainfall is in the range of 50 to 100 cm per year.
4. The arid forest receives less than 50cm of rainfall.
