  • Soil is fertile
  • Grasslands receive from 25 to 39 inches of rain
    during the year

Producer Grass . How does your producer rely on
other organisms in the prairie/grasslands to
survive?
  • Earthworms, beetles, bacteria, and fungi break
    down dead plants and animals-recycle nutrients
  • Wind spreads seeds more grass grows
  • Fires clear area of young or bushes that could
    block sunlight from the grass
