Hints & Solutions

(d) Tropical rain forests occur in equatorial and subequatorial regions. The forests receive all the external inputs for optimum plant growth. Due to abundant plant growth, a large number of animals live in tropical rain forests. In grasslands, fire occur periodically which prevent tree growth. In savannahs, periods of drought are common. In deciduous, forests are found predominantly broad leaved hard wood deciduous trees.
