Worksheet 12- What’s in the Web?
Most animals have more than one thing they like to eat – and more than one thing that likes to eat them too.
Food webs can be used to show more complicated food chains. They can show that most animals eat more than one type of food and that some can have more than one predator.
Look at the information below and complete the food web template in Diagram 1.

The Humboldt Penguin lives mostly on rocky shores near cliffs or on islands along the coasts of Chile and Peru. Chile and Peru are countries in South America. Although Humboldt Penguins live in fairly warm regions, the ocean waters can actually get very cold!
Look at Diagram 1 which shows a Humboldt Penguin.
Read the explanations of each of the penguin’s adaptations.
Work out which body part is being described and write the correct letter next to each of the labels on the diagram.
A - Wings
Penguins don’t f ly. However, these are strong and stiff and have adapted to help the penguin swim underwater. When they are standing on land, on a hot day, they may even spread them away from their body to help them cool down. B - Feathers
These are wind and water-proof and are made up of two parts. The soft and f luffy part traps air to help keep the penguin warm. But, on a hot day they might ruffle these to cool down. The ones that can be seen from the outside are stiff, small and packed closely together.
E - Beak
This is mainly used to catch food but is also used to groom feathers and as a weapon in penguin f ights. Inside there are sharp spines pointed towards the throat that help in swallowing living food such as small f ish.
F - Legs
Penguins have very short ones, which are used underwater for steering. On land, waddling seems to be the easiest way to walk.

Can you imagine what it’s like to be a completely different creature, in a completely different habitat?
Choose one of the animals listed below.
Write a short piece of imaginative writing about a day in that animal’s life. You should explain how it makes good use of the adaptations listed.
Blacktip Reef Shark
The Blacktip Reef Shark has several rows of razor sharp teeth which
they use to catch their prey.
Clownfish
The clownfish is immune to the venom of the sea anemone which it lives in. This helps them to avoid their predators.
Octopus
The octopus has eight legs with suckers on the underside. They use these suckers to help them walk around and to catch their food.
