Part C Using the organisms you identified in part B, create a food web for the ecosystem you chose. Use this
sample food web e for reference, although your food web will contain fewer organisms. Note that your
food web does not have to include images, but you may include them if you choose. However, be sure to
include arrows to indicate the direction of energy flow in your food web. Design your food web using any
method listed below:
• Use drawing or flowchart-building tools in a word-processing program.
• Hand draw your food web, and then take a picture of it.
Use a graphic design program.
Using the Insert Image button, Insert an image of your food web in the answer space.

The diagram shows a fossil of an ancient whale skull and a skull of a present-day whale. the ancient whale is extinct and is believed to be an ancestor of the present-day whale. what do these skulls most likely show that supports darwin’s theory of evolution? all populations can adapt and survive. only some organisms have a common ancestor. populations change slowly over time. populations rapidly become extinct.

Read the following scenario to answer the following question. over the past 60 years, many amphibian species have experienced significant population declines, and some species have become extinct. scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. however, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. these global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. in switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. when most populations of a wide-ranging amphibian species are lost and the few remaining populations are widely separated, we expect to see that a. the founder effect becomes increasingly important b. microevolution no longer occurs c. gene flow between populations is reduced d. artificial selection becomes a greater factor in microevolution

Which statement correctly describes a way that mutations increase the likelihood that a species will survive in a changing environment
