Where is ecosystem located? North and South America Africa and Asia Europe and Australia Everywhere but Antarctica

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 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, Borrowing 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 down 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 over populate Worms would decrease Decomposing would be slower
