Bacteria tend to carbon sources.
There are microorganisms in the world, which are called bacteria. The growth of bacteria also depends on carbon sources for nourishment. Therefore, bacteria often look for carbon sources as their main purpose, and if they have a direction, they will follow them.

Watch the movement of the bacteria, either floating in water, or living in other things. Although the shape is small and ingenious, they do their best in finding carbon sources. Every time they feel the breath of carbon sources, although they are far away from other places, they can also identify them, and then adjust their bodies, turn their direction, and go forward.

Its movement is either slow or fast. When it is slow, if you slowly walk on the path, you can observe the breath at the end of the micro; when it is fast, it is like running through the river, and advancing towards the carbon source quickly. On the way, if you encounter obstacles, you will think about changes, or go around it, or go beyond it, aiming to obtain carbon sources and then move on.

Cover bacteria know that carbon sources are the foundation of life, so they will do their best to follow them. This is why although it is small and can exist, although it is weak and inexhaustible.
