Tropical rainforest (amazonia ) is an ancient complex ecosystem teeming with diverse life forms. High temperatures and rainfall are more or less constant throughout the year producing a warm humid environment. In these hothouse conditions flourish plants and animals are protected from cold and drought . Over time, species have adapted one to another and they tend to get better at using available resources. As species develop into more species need more narrow ecological requirements, that’s why, most of then are specialized species with scarcer niche and the rarest organism.
