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 does this web not tell you?
  2. 2. What does every food chain in this web begin with?
  3. 3. If the frogs disappeared, what would the herons have left to eat?
  4. 4. What breaks down the dead plants and animals?
2.Why can removing one plant affect an animal that never eats it?
  • A.It cannot affect it
  • B.Animals smell plants
  • C.The animals that animal eats may depend on that plant
3.Rabbits were brought to a country where nothing ate them. What happened?
  • A.Nothing changed
  • B.They died out at once
  • C.Their numbers grew huge and they stripped the plants
4.All the decomposers are removed from a sealed tank. What builds up?
  • A.Dead material that is never broken down
  • B.Clean water
  • C.More living plants
5.Ladybirds are released in a greenhouse full of aphids. What happens to the aphids?
  • A.They eat the ladybirds
  • B.They increase
  • C.They fall in number, because ladybirds eat them
6.A forest fire burns the trees. Which animals lose their food first?
  • A.The animals that eat other animals
  • B.Those that eat the leaves and seeds of the trees
  • C.None, fire does not affect food
7.Too many deer graze in a wood. What happens to the young trees?
  • A.Nothing happens to them
  • B.They grow faster
  • C.Many are eaten before they can grow tall
