Tropical rainforests
This biome is home to the greatest number of plant and animal species
Location of rainforests
a belt across central and South America, Western parts of central Africa (it is too dry in the east), in parts of Southeast Asia such as Indonesia and even in Northern Australia.
2000mm+
of rainfall per year
27°C
Minimum average temperature in a tropical rainforest
Latosol
A major soil type of the humid and high temperature tropics with a red or yellow color. Much of the silica has been leached from the soil so tend to be of low fertility.
Nutrient cycling
is fast in the rainforest which allows plants to grow
Water recycling
Roots of plants take up water and rain is intercepted. As the rainforest heats up during the day, the water evaporates into the atmosphere and forms clouds to make the next day's rain.
Stratification
The forest is layered or stratified, as plants try to take advantage of what space and light there is.
Canopy
Dense covering formed by the leafy tops of tall rain forest trees
Emergents
the tallest trees in the rainforest towering above the canopy, such as the capoc
Shrub layer
layer of forest containing shrubs and other short plants
Buttress roots
Large roots that offer stability in the soil
Lianas
Climbing woody vines that drape rainforest trees.
Drip tip leaves
allow the heavy rain to drop off the leaf
Competition
A common demand by two or more organisms upon a limited supply of a resource; for example, food, water, light, space, mates, nesting sites. High in rainforests
Interdependence
the dependence of every organism on its connections with other living and nonliving parts of its environment
