Verified step by step guidance1
Understand the question is asking about which marine aquatic biome covers about three-quarters of Earth's surface.
Recall that Earth's surface is mostly covered by water, and marine ecosystems include oceans, coral reefs, and estuaries.
Identify that freshwater lakes and rivers are part of freshwater biomes, not marine biomes, so they cover a much smaller portion of Earth's surface.
Recognize that tropical rainforests and deserts are terrestrial biomes, so they do not cover large portions of Earth's surface in terms of aquatic biomes.
Conclude that oceans, as the largest marine ecosystem, cover approximately 75% (or three-quarters) of Earth's surface.
