Being a small fish in a freshwater pond is no fun. You’re pretty low on the food chain, and you have to constantly watch your back. Alligators, turtles, birds….. even insects might find you to be a tasty treat!


Food for thought

  • Some fish eat plants. Others eat insects and worms. Bigger fish eat smaller fish. Discuss the various roles that different fish might play in a freshwater ecosystem.


  • Without plants, algae and other producers in an ecosystem, how would the population of predators like alligators or wading birds be effected?


  • In this video, we see several birds with different shaped bills. Each bill is shaped so that it functions in a different way when catching fish. This is what is called specialization. See if you can identify some of these specializations, and how they are used by the particular animal.
