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 the frogs disappeared, what would the herons have left to eat?
  2. 2. If a disease killed the pondweed and algae, what would happen?
  3. 3. What claim does this web support?
  4. 4. What breaks down the dead plants and animals?
2.The rabbits in that field then increase. What happens to the grass?
  • A.It is not affected
  • B.There is less of it, because more rabbits are eating it
  • C.There is more of it
3.A forest fire burns the trees. Which animals lose their food first?
  • A.None, fire does not affect food
  • B.The animals that eat other animals
  • C.Those that eat the leaves and seeds of the trees
4.Why can removing one plant affect an animal that never eats it?
  • A.Animals smell plants
  • B.It cannot affect it
  • C.The animals that animal eats may depend on that plant
5.The foxes are removed from a field. What happens to the rabbits at first?
  • A.They decrease
  • B.They leave at once
  • C.They increase, because fewer are eaten
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.More kinds means less food
  • C.Big webs never change
7.Ladybirds are released in a greenhouse full of aphids. What happens to the aphids?
  • A.They increase
  • B.They fall in number, because ladybirds eat them
  • C.They eat the ladybirds

Answer key — Take One Out of the Web

Set 6. Prints on its own sheet.

  1. 1.1. Only the fish, so the herons would eat more fish. 2. The snails, tadpoles and mayfly larvae would lose their food, and then so would the animals that eat them. 3. Matter moves from the pondweed and algae through the animals to the bacteria and worms, and back to the water. 4. Bacteria and worms in the mud.
  2. 2.There is less of it, because more rabbits are eating it

  4. 4.The animals that animal eats may depend on that plant
  5. 5.They increase, because fewer are eaten
  6. 6.If one food runs short, animals can eat something else
  7. 7.They fall in number, because ladybirds eat them
