The largest biome on Earth is the marine biome. Covering about 71% of the Earth’s surface, the marine biome includes all the saltwater environments, such as oceans, coral reefs, and estuaries. This biome is not only the largest but also the most diverse, supporting a wide range of life forms, from tiny plankton to the largest whales.
The marine biome plays a crucial role in regulating the Earth’s climate and is a vital source of food and resources for humans. It also helps in the production of oxygen and the absorption of carbon dioxide, making it essential for life on Earth.
