Trees have several niches in a forest.  Describe what they are.

                 If the number of snakes in this food web decreases, what will happen to rabbits and hawks at first.

                 If the pine trees are the main habitat for the birds, what will most likely happen to their population if a construction company were to come in and clear a significant number of the trees? How would it also effect the number of insects and owls? Support.

                 If the population of owls decreased, would the Lynx population be greatly affected? Why or why not?

                 If the elk and moose population were reduced because of hunting, how would the wolf population be affected? Explain.

                 Thinking about the concept of biodiversity, which consumer in the food web would LEAST likely be affected of one of their food sources was lost to disease. Support.

                  What are the secondary consumers in this food web?

                 Name the producers in this food web.

                 If their is an increase in the number of lynx, how will that affect the number of fox and eventually the number of mice in the ecosystem?

                the lynx is several kinds of consumers in this web. Name them.

           Using this web, create a food chain that includes the owl.

What do all food chains begin and end with.
