3/15

Summer months usually begin in earlyJune and end in late August

Mild summers averaging about 21C

Winter months begin around December Average temperature during Winter is a

little below freezing


4/15

Almost all of the world's deciduousforests are located by an ocean

The ocean and the wind are two bigfactors of why the temperature andclimate change so much in this biome

More than 18 inches of rain during

summer Almost 14 inches of rain during winter


5/15

Top layer or canopy - Tree Stratum Zone- Height of trees range from 60 feet to100 feet- E.g. oak, beech, maple, chestnut

hickory, elm, basswood, linden, walnut,sweet gum trees

Second layerSaplings, Shorter types oftrees


6/15

Third layerShrub Zone- E.g. rhododendrons, azaleas, mountain

laurel, huckleberries

Fourth layerHerb Zone- E.g. wildflowers, berries

Fifth layerGround Zone- E.g. lichen, mosses


7/15

During summer, deciduous trees broad

leaves capture energy from the sun andconvert it to food by photosynthesising

During autumn, the sunshine becomes

more scarce and the leaves on the treesstop making new chlorophyll.

As the old chlorophyll starts to break

down, the green color of the leaf beginsto go away, revealing brilliant colours(e.g. orange, yellow and red).


8/15

During winter, plants and trees lose theirleaves and seal the places where leaves

were attached with a protectivecovering called a leaf scar

If they kept their leaves, the water in the

leaves would freeze into ice, damagingthe leaves and leaving the plantvulnerable to bacteria or fungi

Plants also make a concentrated sugarsolution to stop water from freezing intheir stems


9/15

Deciduous trees have thick bark toprotect them from the cold weather.


10/15

Deciduous trees have shallow roots. The primary function of these roots is to

absorb water and nutrients. They have extensions (root hairs) which

increase root surface area and increasenutrient and water uptake.


11/15

Tall and wide tree

Tree size is from 90 to 100 feet tall Spreads 50 to 70 feet The bark on the tree is very smooth, pale

and gray The leaves are bright green and about

three inches in length The leaves have distinct, strong veins

and toothed edges.

In the spring, carpet moss is golden

green and turns dark green as it getsolder

Its has sets of parallel leaves, flaps ofchloroplast-containing cells that are longand narrow.

These carry out photosynthesis and mayhelp to conserve moisture by partially

enclosing the gas exchange surfaces.
