How do viruses contribute to the carbon cycle in the ocean?

• By increasing the amount of carbon dioxide in the atmosphere

• By preventing carbon from entering the ocean

• By releasing carbon back into the environment through killing marine microbes

• By absorbing carbon dioxide directly from the atmosphere

What is the potential benefit of manipulating viral populations in the ocean?

• Decreasing the ocean's biodiversity

• Increasing the ocean's temperature

• Reducing the ocean's salinity

• Enhancing the ocean's ability to sequester carbon dioxide

Where was a surprising amount of viral diversity found according to the study?

• Arctic Ocean

• Indian Ocean

• Atlantic Ocean

• Pacific Ocean

What is a key characteristic of viruses that makes their classification challenging?

• They can survive without a host

• They are the largest biotic agents in the world

• They are always beneficial to humans
