Detailed explanation-1: -2 The marine biome is primarily made up of the saltwater oceans. It is the largest biome on planet Earth and covers around 70% of the Earth’s surface and over 90% of life on Earth lives in the ocean.

Detailed explanation-2: -The marine biome is the largest biome on Earth. It covers 71% of our planet, but we have only explored about 5% of its depths. Because the ocean is so big, scientists estimate that more than half of all species (or types of animals and plants) live in the ocean.

Detailed explanation-3: -Ocean Ecosystem. The ocean ecosystem is the largest of the ecosystems found within the marine biome. It is split into four horizontal zones: intertidal, pelagic, benthic, and abyssal.

Detailed explanation-4: -Marine biomes are divided between coral reefs, estuaries, and oceans. The marine biome covers 75% of the earth’s surface, and accounts for 90% of the planet’s water supply.

Detailed explanation-5: -The marine biome is the largest of all the ecosystems. About 70 percent of Earth is covered in oceans, and all of this is included in the marine biome. Of course, the organisms in the marine biome will vary widely depending on what aspect of the biome.
