Biospheric
Characteristics

~ vegetation (autotrophs)
-- Dense luxuriant
-- evergreen
-- complex
-- layered -- emergent / canopy / young tree / shurb / undergrowth
-- epiphytes, climbers, llianas
-- compitetion

1.The dense evergreen forest provides large timber resources e.g. rosewood, ebony, mahogany, etc.
2. Many plant species have medicinal & research value.

***
~ animals (examples)
-- high biodiversity
-- majority live at the canopy

3. There is a great diversity of plants and animals.
a The rainforest landscapes with their flora and fauna offer tourist attraction
(a ecotourism ¥ÍºA®È¹C)
~ Little biomass

~ vegetation (examples)
-- sparse
-- scattered
-- discontinuous
-- low biodiversity
-- oases (around salt lakes)
-- plants with widely spreading root system e.g. American mesquite (deep roots over 50m)

***
~ animals
-- low biodiversity
-- few large mammals
-- insects predominate

1. Herders can only follow the rain to rear drought-tolerant animals e.g. camels, sheeps and goats.

i.e . TRF has a much larger biomass than TD.
The types of animals found in the two places are different too.
