What evidence from the text supports this conclusion?

• “Researchers explored two icebergs in the Weddell Sea near Antarctica. The icebergs began floating after they broke off a sheet of ice that was connected to land.”

• “Plankton are animals and plants that float in seawater. They absorb nutrients from water and sunlight. They are too small to see with your eyes.”

• “The nutrients from the icebergs helped make an ecosystem. An ecosystem is an environment in which animals and plants depend on one another to live.”

• “Petrels and other birds fly between icebergs. They eat the krill and fish that live around icebergs. . . . Some fish, such as silverfish, live in very cold water. They eat plankton, krill, and other small animals.”
