Discussion Questions

1. Why do we (as scientists) build food webs?

I think to measure what animals eat and what are they eaten by, also to distribute the different kinds of animals to different category's. It helps a lot of scientists so they know if it is a carnivore, omnivore or herbivore.

2. Give an example of how one change might affect many other parts of an ecosystem.

Not only it affects several parts, It affects all of the parts because if one animals population, for example the mice, disappears, the hawk wont have allot of things to eat so the hawk population would start decreasing and decreasing, and then bigger animals wont have the hawks to eat so they would decrease and then so on and so fourth.

3. Give an example of how one change in La Quebrada might affect the rest of the ecosystem.

If the plant population wouldn't exist in the quebrada we wouldn't have as many diversity and different types of animals that in these days we have. And with more diversity better because more animals could come and enjoy the quebrada as a home.
