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

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).

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

absorb water and nutrients. They have extensions (root hairs) which
increase root surface area and increasenutrient and water uptake.

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.
