3 Forests
Abiotic Factors
Nonliving parts
influence
• The
populations
of plants
of animals
• That live in an
area
Biome
 Geographic area
characterized by
certain types of
• Plant communities
• Animal communities

Made up of smaller
ecosystems
• Ex: Tropical Rain Forest
 Canopy
 River
 Forest floor
 Etc.
Three types
Depends upon
• Abiotic factors
• Temperature
• Precipitation
Tree populations
 Deciduous trees that
loose leaves in winter
• To conserve water

Tree populations
 Evergreen trees,
mostly conifers
• Waxy coated needles
prevent drying out
during winter

Biotic Animals
Tree populations
 Most biologically
diverse
• More species than any
other biome
• Ex. 100 species in area
equal to ¼ a football
field
• Canopy
 Preferred living site
 1,400 different species of
birds
Tree populations
 Tall Broadleaf Trees
• Waxy coated leaves to
shed water
• Leaves with drip tip
Abiotic
