Trees which form strata or layers, the tallest being 30 to 45 meters high (100-170 feet tall)
Smaller trees, shrubs, and vines form a subcanopy and
epiphytes (bromeliads and orchids) find a foothold on other plants.
Incredible array of plant and animal species utilizing every available niche -- biodiversity found in rain forests has provided mankind with numerous medicines and food sources.
