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 does this web not tell you?
  4. 4. What breaks down the dead plants and animals?
2.Why can removing one plant affect an animal that never eats it?
  • A.Animals smell plants
  • B.The animals that animal eats may depend on that plant
  • C.It cannot affect it
3.A farmer sprays a field to kill every insect. What could happen to birds that eat insects?
  • A.They get more food
  • B.They have less food, so fewer survive
  • C.They start eating the spray
4.A new road cuts a wood in two. What is one effect on the animals?
  • A.Some can no longer reach food or mates on the other side
  • B.None at all
  • C.They all get more food
5.Gray squirrels were brought into Britain. What happened to the red squirrels?
  • A.They declined, partly because the gray squirrels took their food
  • B.They ate the gray squirrels
  • C.They increased
6.The foxes are removed from a field. What happens to the rabbits at first?
  • A.They increase, because fewer are eaten
  • B.They decrease
  • C.They leave at once
7.All the decomposers are removed from a sealed tank. What builds up?
  • A.Clean water
  • B.More living plants
  • C.Dead material that is never broken down
