The duck is the primary consumer and the eels are secondary consumers. Phytoplankton is both consumer and producer, and the arrow show who eats who. The duck eats the caddis and the caddis eats phytoplankton and decaying organic matter
The fish hide in the weeds from predator the weed is unaffected
Eel gets its teeth clean and cleaner fish gets food
The leeches feed off the fish and the fish dies
