The given image represents the information about food chain. According to the image, we can see the first step is that bees pollinate flowers from the green trees, followed by the second step that small fish eat those bees. The third step is that the small fish grow up into big ones. The fourth step is that the big fish are eaten by a grizzly bear and fish bones remain. According to this graph, the next step is that grizzly bears die and decay, and their skeletons remain, which nourishes trees. In conclusion, the whole process will repeat which represents how the whole process is done.
