Take One Out of the Web is a free printable Grade 5 science worksheet on predicting how a change to one part of a food web affects the rest, aligned to NGSS performance expectation 5-LS2-1. It prints 7 questions with an answer key on its own sheet of paper, in 25 versions that each ask different questions, so no two students in the class work from the same page. Print it from the browser or download it as a PDF — no account, no email.

Read the food web, then answer the questions.

1.Read the record, then answer the questions.

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. If a disease killed the pondweed and algae, what would happen?
  2. 2. What eats the mayfly larvae?
  3. 3. If every snail were taken out, which animals would lose some of their food?
  4. 4. What breaks down the dead plants and animals?
2.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
3.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.There is more of it
  • C.It is not affected
4.Gray squirrels were brought into Britain. What happened to the red squirrels?
  • A.They ate the gray squirrels
  • B.They declined, partly because the gray squirrels took their food
  • C.They increased
5.A forest fire burns the trees. Which animals lose their food first?
  • A.Those that eat the leaves and seeds of the trees
  • B.The animals that eat other animals
  • C.None, fire does not affect food
6.Why does a web with many kinds of living thing cope better with a change?
  • A.If one food runs short, animals can eat something else
  • B.Big webs never change
  • C.More kinds means less food
7.Why can removing one plant affect an animal that never eats it?
  • A.The animals that animal eats may depend on that plant
  • B.It cannot affect it
  • C.Animals smell plants
