Describe the abiotic factors of your ecosystem Temperature is usually 75 degrees F
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
How do other organisms of your ecosystem rely on your producer to survive? Prairie Dogs, Kangaroo Rats, Ferrets, Skunks,
Bobcats, Pocket Mice, Burrowing Owls, American Badgers, and Gophers are some of the animals that need burrows for shelter
Grass provides food for Cattle, Bison, Elk, and insects
How do humans affect your ecosystem? Large parts of Grasslands get plowed for farms
People go on safaris to shoot lions and other large animals
Native Americans started and controlled fires for good nutrients
People collect grass seeds to replant grass
Choose one biotic or abiotic factor in your ecosystem & describe how a change in one of these could your ecosystem. Change: If you take away bull snakes
Rodents and birds would overpopulate
Worms would decrease
Decomposing would be slower
Other interesting facts:
Grasslands have very little trees and bushes
There are a lot of different types of grass
