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. Only a small amount of water reaches the forest floor as the leaves act as shields. The temperature range is between 25 to 35 degrees Celsius due to the rainforest's proximity to the equator, allowing for faster 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.
