Grassland Prairie by liaoqinmei


By: Michael, Tom, Stephanie, Ashley
• Grasslands can be located in the middle of
  north America where grass and wild flowers
  were. They can also be found in south
  America, Europe, Australia, Africa and in a
  little bit of Asia
Grassland prairies are replete with grass
and all different kinds. Some of the
different kinds of grass include blue stem
grass and Indian grass. Living in the
Prairie its like you are living in a sea of
grass. Animals like to eat this for food.
Grassland Prairies don’t have many
physical features but they do have a
couple of plateaus. Plateaus are flat
topped mountains.
Human influence on The Grassland
 Humans influence the Grassland prairies by
 making sure that they plant mostly thick bark
 tree and long rooted plants. We also
 influence grasslands by setting off fires
 (accidental or not). Sometimes we introduce
 native plants that can sometimes affect the
 growth of the original plants that were already
 there. Farming has caused an increase
 amount of soil erosion.
           Weather & Climate
• The prairie gets 25 to 76 centimeter
• The grassland gets 10 to 12 hr of sunlight in a
• The humidity in the grassland gets so dry
  sometimes the biome has wild fires
• The average temperature for the grassland in
  summer is 70 degrees & -40 in winter
             Weather patterns
• Another weather pattern are droughts. Droughts are
  easily found because of the lack of water. They occur
  in the summer
• Another weather pattern is rain. This occurs from
  late spring to early summer
• Another weather pattern is wind. There are pretty
  fast speeds. This is because there are not very many
  trees so nothing can slow them down. This happens
  all year.
The results of the weather patterns
• When the droughts occur theirs lack of rain so there
  is not enough rain for the plants and animals that live
  there, so the animals may die of thirst & hunger.
• When it rains, it gives the plants water & it gives the
  animals that live there water to drink.
• When the wind picks up to fast speeds it effects the
  plants because the wind might pick up the loose soil.
The Soil Helps Plants grow by when its rains the
soil will slowly dissolve into the plants stem and
sometimes it might rain to much which causes
some water to just sit there and do nothing.
Water can feed the plants later with the left over
water. Climate can help plants by helping it grow.
In the Winter the plants are regenerating under
the snow. In the Spring clouds bring rain that
feeds and water the plants. In the Summer the
sun gives Sunlight that helps grow the plant. In
the Fall plants die when they are drowned out by
too much rain and the cold.
   The Sunlight helps plants by giving off food and sun.
   Ten Plant Species are
1. Shrubs
2. Milkweed Flower
3. Cone Flower
4. Prairie Blazingstar
5. Stinging Nettle Plant
6. Poison Ivy
7. Silver Maple Tree
8. Blue Stem Grass
9. Indian Grass
10.Butterfly Weed
For plants to survive they must be able to adapt to most types of weather. They
 have warm warm summers and very cold winters. Fires and droughts are common
 here. They receive around 10- 30 inches of rain per year. So most of the plants
 must be prepared for any kind of weather. Plants must also be able to adapt to
 their prey. If a predator comes and tries to attack or pounce they can easily blend
 in. During fires Shrubs will easily re grow. Some prairie trees have thick trunks to
 be protected from fire. Also many grasses take advantage of exposed windy
 conditions and are wind pollinated
                 Abiotic and Biotic
Abiotic and biotic factors are very important to the animals that live in
the grass lands. Rocks (abiotic) provide a home/protection form other
animals. Plants (biotic) provide food for all animals (mice, bunnies,

Halobacteria Is the decomposer that lives in the grassland prairie. It
decomposers all of the dead animals for nutrition. It also cleans up the
mess of animal wastes so the animals don’t step in something every time
they put there foot down.
Herbivores and Carnivores

     Herbivores    Carnivore
     Mice          Kestrel
     Bunny         Fox

     Grasshopper   Hawk
           Food Chain
 P1= Primary consumer
 P2= Secondary consumer

  P2                       P2


Producer                  Producer
   As you can see the mouse, grasshopper, fox, and
bunny adapt to there envierment by blending in. on
the other hand the hawk and the kestrel adapt to
there envierment by having super sharp vision and
flying super fast.
