Ecosystems: Food Web Changes
CW: Students create two similar food webs that feature the animals before and after wolves are introduced. The words should be written in sizes proportional to their population. Big words for big populations. Small words for small populations. (Note: Producers will always be the largest word; wolves are a small population; and don’t forget to include coyotes, rabbits, deer, bears, etc.)
DN: What would happen if a species was removed from a food web?
EQ: How does adding or removing a species from a food web affect the population of the other species?
