11. Read the extract below and then answer the question on it.
Sunlight radiating heat, visible light, and ultraviolet light is the source of almost
all life on Earth. Everything you see alive around you is there because a plant
somewhere was able to capture sunlight and store it. All animals live from these
plants, whether directly (as with herbivores) or indirectly (as with carnivores, which
eat the herbivores). This is true of mammals, insects, birds, amphibians, reptiles, and
bacteria, everything living. Every life form on the surface of this planet is here
because a plant was able to gather sunlight and store it, and something else was able
to eat that plant and take that sunlight energy in to power its body

The text above highlights the importance of a phenomenon that involves all living
things and that we study in Biology class. That phenomenon is
• solar radiation.
• how the human body works.
. the process of photosynthesis.
• cellular organization. ​
