1.a) Insects,Squirrels and other small rodents and Pronghorn and other grazers.
b) Raptors and Badgers
c) Bats, lizards and small reptiles
d) No organism eats mountain lions
2. Killing coyotes for absolutely no reason with no organism to feed on it might cause various factors to the organisms in this food web. First, the coyote population would decrease leaving no or less predators for the prey, the pronghorn and other grazers. This could cause an increase on their population leading to more plants being consumed and decreasing the amount of plants thus leaving less food for herbivores such as squirrels, insects or even humans causing a decrease to most of their populations.
3. This increase of the mountain lion population could cause its prey, prong horn and other grazers to decrease, leaving coyotes with half the supply of food they already had allowing its prey to reproduce and increase in population. Other effects such as the decrease of pronghorns and other grazers could cause plants to increase leaving the other primary consumers, insects squirrels and other small rodents, with more food, increasing their population. This will give the predators of these organisms more prey to feed on and also increasing their population. So, this all moves in a big cycle and all animals are interdependent upon each other balancing out this food web.
4. Mesquite trees require a great deal of water leaving other plants with no water to germinate. This could cause a great decrease in other plants causing primary consumers to decrease which will eventually affect all organisms in the ecosystem. Many animals feed on seed pods produced by the mesquite trees, this could balance out the food web and giving primary consumers food to feed on and continuing the food web as it was at first.
