Tropical rainforests have an emergent layer of tall trees over 40 m tall, an overstory of trees up to 30 m tall, a sub-canopy layer of trees and tall shrubs, and a ground layer of herbaceous vegetation. Tropical forests have the highest biodiversity and primary productivity of any of the terrestrial biomes.
What ecosystem has a lot of trees?
Forests are dominated by trees, and cover about one-third of the Earth. Forests contain much of the world’s terrestrial biodiversity, including insects, birds, and mammals. The three major forest biomes are temperate forests, tropical forests, and boreal forests (also known as the taiga).

What is an ecosystem of a tree?

How many main ecosystems are there?
The Encyclopedia of Global Warming and Climate Change, Volume 1 identifies eight major ecosystems: temperate forest, tropical rain forests, deserts, grasslands, the taiga, the tundra, the chaparral and the ocean.
Which ecosystem most likely has the greatest biological diversity?
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.
