Food Web in the Sagebrush-Steppe Ecosystem

1)
a - Squirrels and other small rodents, insects, pronghorn and other grazers.
b - Badger and raptor
c - Bats, lizards and small reptiles
d - no one 

2) The coyote eats lizards and other reptiles who also eat insects, so this will effect both animals because there will be a lot more of them. The mountain lion would be affected because i also eats the pronghorn and other grazers. 

3) If there was an increase in mountain lions there would be a lot less pronghorns and other grazers around because they are the only animal that the mountain lion eats.

4) The effects the mesquite trees would have on the ecosystem is they take so much water form the soil that plants won't be able to grow quickly. However they are edible so they would be very useful to humans and they also produce seed pods which are eaten by animals and they're good because they put nutrients back into the soil. So the only down part is for the plants.

  2. Haya,

    Good job getting your blog up and running. I need you to do several things. I like the quality of answers especially the thought you gave number four. You need to get caught up with the latest homework. Make your food web and answer the questions and post up on your blog. Looking forward to seeing the updates.

    Be sure to follow your own blog so you can see when I send you messages.

    Mr. Rhodes
