What is a Deciduous Forest?
• A deciduous forest
  is a cool rainy area
• The trees lose
  their leaves in fall
  & re-grow them in
  Spring
• Known for color
  changing leaves
• Has 4 distinct
  seasons
  Environmental Conditions
• The Average temperature is 75
  degrees although it can get up to 86
  degrees
• Most of this forest is in NE America
• 2-5 ft. of precipitation a year
• Humidity is 60%-80%
• 6 month growing period
• Subtropical climate
       Environment (cont.)
• Warm summers           • Very rich soil
• Fairly short winters   • Leaves fall in fall &
• Rainfall every month     decay quickly in
  of the year              spring
• Trees change color     • Daylight decreases
  w/ season                in fall
• Winds blow west-       • 3/4 of these
  east                     forests are in

  trees.

         Biotic Substances
• Animals
         – Carnivores-
           ex.Ocelot
         – Herbivores-
           ex. Deer
         – Omnivores-
           ex. Bear
         – Decomposers-
           ex. Bear
       Biotic Substances
• Plants-
       – producers- ex. fern
       –            ex. Tree
       –            ex. Flower
       –            ex. Vine
         Abiotic Substances
• Sun-
         – Gives light for PHOTOSYNTHESIS

• Water-
         – Animals drink it and cool off in it
         – Habitat
         – Replenished by PRECIPITATION
          Abiotic Substances
• Soil-
          – Habitat
          – Everything grows on it

• Air-
          – We breathe it.
          – It is recycled in PHOTOSYNTHESIS

              Five Layers
• Tree Stratum- 60-100 ft. high, dominated
  regionally by combinations of trees
• Sapling layer- Smaller trees or younger
  species of taller trees
• Shrub layer- members of the heath family
• Herb layer- bloom in early spring
• Ground layer- layer of lichens, club mosses,
  and true mosses

            The Ocelot
• A medium sized slim cat
• 1 litter 0f 2-4 born after a gestation
  of 70 days
• Climbs well and silently
• Main food is small animals and birds.
• Ocelot population has declined
  because of deforestation and human
  intervention
         Predators and Prey
•   The rabbit will eat the grass
•   The ocelot will eat the rabbit
•   The ocelot will die
•   Worms and mushrooms will eat the ocelot

           Conclusion
Although the deciduous forests are
shrinking because of deforestation
etc. these forests are still a place of
abundant life, beauty, and animals.
