Which ecosystems are the most common comprising 75 percent of Earth’s surface?
Ocean ecosystems are the most common, comprising 75 percent of the Earth’s surface and consisting of three basic types: shallow ocean, deep ocean water, and deep ocean surfaces (the low depth areas of the deep oceans).
Which of the following biomes occupy most of Earth’s surface area?
Worldwide, the aquatic biome can be broken down into two basic regions, freshwater (ponds, lakes, streams, rivers, wetlands) and marine (oceans, coral reefs, estuaries). It makes up the largest part of the biosphere, covering nearly 75% of the Earth’s surface.

Which ecosystem makes up 75% of Earth’s surface quizlet?
Ocean ecosystems are the most common, comprising 75 percent of the Earth’s surface.
How does biosphere depend on the atmosphere and hydrosphere to survive?
For instance, plants (biosphere) grow in the ground (geosphere), but to survive they absorb water (hydrosphere) and carbon dioxide (atmosphere). Nor are plants merely absorbing: they also give back oxygen to the atmosphere, and by providing nutrition to animals, they contribute to the biosphere.
