With the second picture what the freak is a food

Like a Food chain, so something eats something to grow

An example of a food web is the plant absorbs the sunlight (producer). The grasshopper eats the plant (primary consumer). The hawk (tertiary consumer), spider, weasel, and shrew (all secondary consumers) eats the grasshopper. The spider is eaten by the weasel and shrew. The shrew is eaten by the hawk, weasel, and owl (tertiary consumer). The weasel is eaten by the hawk and owl. The hawk is eaten by the owl. The owl is the head of the food web.
I really hope this made sense and hope it helped!:)
