Earth’s ecosystems range from wild to mild. One of the wildest and most diverse is the Amazon rainforest of South America.
Altogether, this biome and the ecosystems within it host about 40,000 plant species, 1,300 bird species, 427 mammal species, and 2.5 million types of insects. A lot of them live in the tree canopy, where sunlight reaches. Under the canopy, it’s dark. Flowers bloom big and bright. That way, insects and birds can spot them and spread the flowers’ pollen.
