Plants
• Plant Adaptations: plants
• Great Lobelia
lean toward sun to get
energy, leaves shed in cold • Oak
• Lichen
• 5 zones: tall tree, small
tree, shrub, herb, ground
• Trees can grow to 100 feet
• Many middle sized trees
and shrubs
• Small forest floor plants
and lichen

Lichen
• 8% of vegetation
• Fungi
• Grows with a partner
like algae
