• Question 9: Energy flows from prey to predator. Lemming is prey to snowy owl, so energy flows from lemming to snowy owl.
• Question 10: Arctic hare and lemming are both primary consumers, so there is no energy flow from arctic hare to lemming.
• Question 11: Decomposers like bacteria and fungi that break down dead organisms are missing from the food - web diagram.
• Question 12: Wolf is at the top of the food - web and preys on other animals, so it is likely the apex predator.
