Boreal forest climate is characterized by; low temperature, moderate precipitation and humidity, as well as variable solar radiation and atmospheric pressure.
Characteristics of tropical rainforest ecosystem are; warm-humid climate, high precipitation, complex vegetative structure, low-fertility acidic soil and high biodiversity.
Tropical rainforest climate is characterized by; abundant rainfall, solar radiation, high relative-humidity, warm temperature, and relatively-high atmospheric pressure.
Tropical rainforest animals are; mammals (including primates, felines, bats, rodents) birds, aquatic animals, arachnids and insects, as well as reptiles and amphibians.
