TROPICAL RAINFOREST DEJAH BRINSON & LOGAN MCINTOSH
LOCATION OF BIOME • Tropical rainforest re located near the equator. • Fifty seven percent of all tropical rainforests are found in Latin America. • One third of the world's tropical rainforests are in Brazil. • Other tropical rainforests are located in Southeast Asia and the Pacific Islands
Climate OF BIOME • Tropical rainforest have year round warmth • Average of 50 to 260 inches of rainfall yearly • Temperature rarely gets higher than 93 degrees or lower than 68 degrees • Humidity is between 77 to 88% • Does not have 4 seasons • Stable climate does not allow the biome to have a wet/dry season
SOIL WITHIN THE BIOME • Soil in the tropical rainforests is very nutrient poor • The topsoil is only one to two inches deep • The soil makes the plant life lush • Plants store nutrient themselves instead of getting it from the soil
PLANTS in THE BIOME • Plants adapt in the tropical rainforest by using the trees for sunlight • Plants found in tropical rainforest... • Buttresses- have big shallow roots to support the trees. • Lianas- grows into canopy for sunlight. • Orchids- thin smooth bark. • Carnivorous plants- have a cavity filled with sweet or terrible smelling nectar that attract insects. • The aerial plants- accumulate nutrition from the air

Endangered species • Gorilla- extinct because of habitat loss and disease • Orangutan- habitat loss, hunting and trapping for trade • Jaguar- loss of habitat and threat of poachers • Toucan- habitat loss and capture for commercial (pet markets) • Bengal Tiger- Large-scale poaching and habitat loss • CITES is a law to protect wildlife against exploitation in the tropical rainforest.
Threats to the biome • The greatest cause of tropical rainforest destruction today comes from human activities such as…….. • Oil extraction • Logging • Mining • Fires • War • Commercial agriculture • Cattle ranching • Hunting • All this can lead to deforestation
