When Darwin was in the Galapagos islands, he noticed there were a variety of finches that existed on each of the islands. There were many different species of finch which differed in beak shape and overall size. This is adaptive radiation and natural selection at work. Remember the "sun" that Mrs. Stein drew? The adaptive radiation picture looks like a sun, because 1 species gave rise to many species.

Sorry Mike H I can't comment on your post, because...I don't know how to...
So here's my advice about your problem. (The first image is a better example!)


Well, do you know that:
1st trophic level is producer
2nd is primary consumer (Herbivores)
3rd is secondary consumer. (Consumers)
Remember that producers are autotrophs that makes their own food; i.e. plants, bacteria's.
And consumers are heterotrophs which cannot make its own food, so they rely on producers or other consumers; i.e. animals, humans.
