Answer:
3. Rainforests are the lungs of the planet. Plants absorb carbon dioxide from the air and replace it with oxygen. Rainforests like the Amazon act as carbon sinks that offset the carbon dioxide that is released into the atmosphere.
4. The animals living in the emergent layer of the Amazon rainforest include birds, bats, gliders, and butterflies. Large raptors, such as white-tailed hawks and harpy eagles, are its top predators. In rainforests on the island of New Guinea, pygmy gliders populate the emergent layer.
5. The rainforest canopy - An estimated 50-90 percent of life in the rainforest exists in the trees, above the shaded forest floor.
6. The understory is the warm, damp, and sheltered layer below the leafy tree canopy. Rain drips through the canopy, but only speckled sunlight gets through. Large-leafed shrubs that are suited to the warmth, shade, and moisture grow here. Smaller trees grow in patches of sunlight.
7. Plants that are found on the forest floor:
Giant Water Lily, Victoria Amazonica.
Heliconia, Heliconia latispatha.
Cacao, Theobroma cacao.
Passion flower, Passiflora edulis.
Coffee Plant, Coffea arabica.
Monkey Brush Vines, Combretum rotundifolium.
Orchid, Orchidaceae.
