Who Eats What in Our Pond

A food web the class drew from a term of pond-dipping records. WHO EATS WHAT Pondweed and algae are eaten by snails, tadpoles and mayfly larvae. Mayfly larvae are eaten by newts and fish. Snails are eaten by newts and frogs. Tadpoles are eaten by newts and fish. Frogs and fish are eaten by herons. Dead plants, dead animals and droppings are broken down by bacteria and worms in the mud, returning matter to the water.

  1. 1. What claim does this web support?
  2. 2. What does every food chain in this web begin with?
  3. 3. What breaks down the dead plants and animals?
  4. 4. What does this web not tell you?
2.Why can removing one plant affect an animal that never eats it?
  • A.It cannot affect it
  • B.The animals that animal eats may depend on that plant
  • C.Animals smell plants
3.All the decomposers are removed from a sealed tank. What builds up?
  • A.Dead material that is never broken down
  • B.More living plants
  • C.Clean water
4.The foxes are removed from a field. What happens to the rabbits at first?
  • A.They leave at once
  • B.They decrease
  • C.They increase, because fewer are eaten
5.The rabbits in that field then increase. What happens to the grass?
  • A.There is less of it, because more rabbits are eating it
  • B.It is not affected
  • C.There is more of it
6.Too many deer graze in a wood. What happens to the young trees?
  • A.They grow faster
  • B.Nothing happens to them
  • C.Many are eaten before they can grow tall
7.A forest fire burns the trees. Which animals lose their food first?
  • A.None, fire does not affect food
  • B.Those that eat the leaves and seeds of the trees
  • C.The animals that eat other animals
