Question 8 options:

A)

Trees

B)

Oil

C)

Energy source

D)

Sunlight

Answer 1

The requirement of every single natural process on Earth is primarily an **energy source**. Therefore, the correct answer is:

**C) Energy source**

All natural processes, such as photosynthesis, respiration, and various geological processes, fundamentally rely on some form of energy. While sunlight is a significant energy source for many processes (particularly in ecosystems), not every natural process depends exclusively on sunlight; other sources of energy, such as geothermal energy or chemical energy, also play roles in various processes on Earth.
