4-6-5-2-3-1
4-5-6-2-1-3

Answer

B. 4-5-6-2-3-1

Solution

The correct order is 4-5-6-2-3-1. Each sentence picks up an idea from the one before it: Plants make their own food through a process called photosynthesis. In this process, they capture energy from sunlight using a green pigment called chlorophyll. That energy is used to combine carbon dioxide from the air with water drawn up from the roots. The result is glucose, a sugar the plant uses for energy and growth. Along with the glucose, oxygen is released as a by-product. It is this oxygen that most animals, including humans, depend on to breathe. Each wrong choice swaps just one pair of neighboring sentences, which breaks one of these links.
