At a fundamental level, marine life affects the nature of the planet. Marine organisms, mostly microorganisms, produce oxygen and sequester carbon. Marine life in part shape and protect shorelines, and some marine organisms even help create new land (e.g. coral building reefs).
Why is there life in the ocean?
A Global Reservoir of Life
The ocean represents our planet's largest habitat and supports more than half its species. Photosynthesis in the ocean plays a vital role in the global climate and carbon cycle and provides about half of Earth's oxygen.
Why do animals live in the ocean?
Food is scarce in much of the deep sea, in part because photosynthesis only takes place at the ocean's surface where there's sunlight. Most animals cope with this by being very small and needing less to eat or by growing very slowly.
