Answer:
The correct answer is Temperature.
Step-by-step explanation:
Arctic penguins live in thick ice sheets most of the time, due to the extremely cold climate. Others live on sandy beaches and small islands.
All penguins have something in common, they live near the sea where they can hunt and feed. These animals need to feed on a large number of fish, krill, squid, and crustaceans to survive. It is for this reason that they live mainly near cold-water streams, as it is from these streams that they can extract large amounts of food.
Have a nice day!
