Tropical Forest Biomes By: Adriana N. and Alex A. Climate There are two types of Tropical Forests: Rain and Deciduous Two seasons, rainy and dry No winter Temperature only varies by 5 C from cold/warm Average Temp: 20-25 C Average Rainfall: 200 cm Limiting Factors Poor soil nutrients that are acidic Rapid decomposition, soils leach nutrients and water Near equator 12 hours of sun light More that one half tropical forest have already been destroyed Flora 1 Sq. km over 100 tree species Usually 25-35 m tall Shallow roots, smooth bark Lianas-Climbing vines that reach from the soil to the canopy Epiphytes (orchids, bromeliads)- attach to branches of trees to obtain nutrients from organic matter falling from the canopy. Buttresses-Large bulges at the base of trees for support Fauna Animals usually only eat a specific kind of food because of competition Camouflage- Many animals use camouflage to hide from predators Bright Colors- Some animals use bright colors to warn off curious animals while others use it for attracting a mate. Highest degree of biodiversity in an ecosystem. About 50% of world’s species live in the rainforests Biomass Pyramid Ocelot (Highest Level Consumer) Green Tree Snake (2nd to high level consumer) Tree Frog (1st to 2nd Consumer) Ants (Producer to 1st Consumer Bromeliad (Producer) Bibliography Miller, Jr., Tyler G.
