What Are Rainforests Like? (05:26)

FREE PREVIEW

See market day in Coca. Rainforests are the world's most diverse ecosystem. Approximately 25% of all medicines derive from rainforest species. Rainforests led to the evolution of complex food webs.

Where and Why do Rainforests Grow? (04:30)

Primary forests require year-round solar energy and significant rain; photosynthesis is the reason for rainforest greenery. See maps of net primary productivity and global patterns of precipitation. Mature rainforests convert 2.2 kg of carbon into biomass.

Soils and the Nutrient Cycle (04:43)

High temperatures and humidity result in efficient movement of nutrients from dead organisms to living plants. Tropical rainforest soil has a thin layer of humus. Soil fertility restoration after deforestation is a challenge.

Structure and Adaptation (07:29)

Rainforest have distinct stratification; less than 3% of light reaches the forest floor. Drip tips on leaves and smooth bark allows heavy water to flow off trees. Trees developed adaptations to accommodate evapotranspiration and established relationships with mycorrhizal fungi. Some species "hitch rides" on trees or work with animals and birds to reach the canopy, others receive nutrients from water and air.

Description

Let our drone take you on a visual journey through the extraordinary biodiversity of the Amazon rainforest, providing fantastic examples of adaptation, stratification and competition. From the forest floor to way up in the canopy, this title explores the tropical rainforest's distinct biotic and abiotic characteristics and the conditions that help create this biodiversity hotspot. Climate, soil profile, nutrient and water cycles, are all considered, as is their interdependence with flora and fauna.
