  1. North American Grasslands Biome Research By JeraDavis http://grmsbiomes.pbworks.com/w/page/23239314/Abiotic%20Factors%20-%20Grassland

  2. Name of BiomeGeography & Climate • Location: American Prairie Grassland • Description: land dominated by climax communities grass and a few trees • Soil type: fertile and rich • Precipitation:10-30 inches per-year • Climate: hot summers, cold and snowy winters; various changes in seasons

  3. Name of BiomeBiodiversity • Plant species: tall grass, mixed grass, short grass, corn, wheat, flowering plants. • Animal species: pronghorn, antelope, mule, deer, elk, black bears, foxes, badgers, black-footed ferrets, rabbits, burrowing owl, eagles, hawks, grouse, ducks, birds, small insects, and snakes. This is a North American prairie fox.

  4. Name of BiomeAdaptations Needed for Survival • Plant adaptations: grass- wildfires periodically destroys dry grass and encourages new growth. Deep roots to hold grass is the soil. • Animal adaptations-burrowing helps animals to survive.

  5. Name of BiomeInteractions of Biotic and Abiotic • Biotic- burrowing animals, grass, birds. • Abiotic -dirt, water, and air.

  6. What is Biodiversity? • Biodiversity-a variety of life. It can be studied on many different levels. At the highest level, you can look at all the different species o the entire earth. On a much smaller scale you can study biodiversity within a pond or a neighbrohood park.
