The correct answer is D. Ocean.<\/p>\n
Oceans are the most stable ecosystems on Earth. They cover over 70% of the planet’s surface and contain over 97% of the Earth’s water. The ocean is home to a vast array of life, including fish, coral reefs, and plankton. The ocean is also a major source of food and oxygen for humans.<\/p>\n
Forests are also relatively stable ecosystems. They are home to a variety of plants and animals, and they play an important role in the Earth’s climate. However, forests are more susceptible to changes in climate than oceans.<\/p>\n
Mountains are less stable ecosystems than forests or oceans. They are home to a variety of plants and animals, but they are also more susceptible to changes in climate and human activity.<\/p>\n
Deserts are the least stable ecosystems on Earth. They are home to a variety of plants and animals, but they are also very sensitive to changes in climate and human activity.<\/p>\n
In conclusion, the ocean is the most stable ecosystem on Earth. It is home to a vast array of life, and it plays an important role in the Earth’s climate.<\/p>\n","protected":false},"excerpt":{"rendered":"
