The document discusses the abiotic components of a rainforest ecosystem. It notes that rainfall is the chief climate component, averaging 250 cm per year, and is influenced by the forest's equatorial location. The humidity beneath the canopy is high due to transpiration. Temperature in the rainforest ranges from 25 to 35 degrees Celsius due to its proximity to the equator, allowing for fast growth and decomposition.

1. RAINFOREST ECOSYSTEM

2. ABIOTIC COMPONENTS – RAINFALL/WATER
• Water/ Rainfall -> Directed by sunlight -> Chief Component in
Climate -> Influenced by its equatorial location -> Hot and Wet
• Amount of Rainfall -> Determines biodiversity, growth and
appearance. -> Distinct Characteristics
• Humidity is greater beneath the canopy -> Transpiration
• Rainfall -> 250 cm per year.
• Uniqueness of Rainforest -> Its precipitation comes from its own
evaporation as opposed to others (their evaporation will have to be
carried in far away areas.)

3. ABIOTIC COMPONENTS – RAINFALL/WATER
• Only a small amount of water reaches the forest floor->
Leaves act as shields.
• Average Temp is 18 deg C.

4. TEMPERATURE
• Temperature range in tropical rainforest is between 25 to 35 degrees Celsius
• This high temperature range is explained by the closeness of the rainforest to
the equator. Since it gets the most sunlight in comparison to other rainforests
because of its location, it normally gets high temperature.
• This allows faster growth on most organisms since they don’t need to use
energy to conserve heat. They can spend their energy on feeding and
reproduction.
• Decomposition happens at a faster rate because most decomposers are active
in high temperature.
