Discussion Questions

Why do we as scientists build food webs?

We build food webs to see how energy is being transfered throughout nature and and its ecosystems. Food webs are also built to show how the animals and world would react to a small or big change like the increase in an animals population or the decrease in anothers. They are a way to see what will happen in extreme situations.

Give and example of how one change might effect the entire ecosystem

One example of a change would be if the bear population decreased the fish population would increase and then the otters population would increase and then the alligator population would increase which in turn would make the population of everything the alligator eats decrease and so on.
The balanced ecosystem from before would shift but it would be a new balance. Changed but balanced none the less
