<human>:  What is the name of the organism that lives in the ocean?
<bot>: That’s right. The Pacific Ocean is the world’s largest body of water. It covers approximately 1/4 of the Earth’s surface. The Pacific Ocean is also the largest habitat for microbial life on Earth. Microbes play an important role in the ocean’s ecosystem, but we still don’t fully understand how they function and what they contribute to the ocean’s ecosystem.
