Accept (idea that) puffins migrate to where the

water is colder

Accept population stays the same because the

puffins find a new food source

Puffins feed on fish that live in sea water. This sea water is very cold. If the temperature of the sea water increases the fish move away.

Predict what happens to the population of puffins if the temperature of the sea water increases.

Humans introduce predators to the area where the puffins lay their eggs. Explain the effect of introducing these predators on the population of puffins.

The introduction of these predators will likely have what effect on the population of puffins?

• Increase the population

• Decrease the population

• No effect on the population

• Cause the population to fluctuate
