Answer:
The tropical forests, comprising cloud forests, evergreen rainforests, mangrove forests, and seasonal deciduous forests exhibit the highest biodiversity of all the terrestrial biomes. The tropical rainforests specifically occupy less than 7% of the surface of the Earth, however, is a habitat for about half of all the prevailing animal and plant species.
While the dry tropical forests comprise some of the species identical to rainforests, however, the number of overall species falls down. Of the prime temperate forest types, that is, temperate rainforest, coniferous, mixed, and deciduous forests, the temperate deciduous and the mixed forests that constitute both the coniferous and deciduous species exhibit the highest biodiversity. Some of the temperate coniferous forests comprise only few of the tree species, however, it comprises great diversity of birds.
