Species richness is greatest in tropical ecosystems. Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.
Which ecosystem has the most species?
Do you know that more than 40 percent of world’s animal and plant species live or breed in wetlands? This incredible figure makes wetlands the most biologically diverse ecosystem in the world.
