1. Antarctic food chain – information
Read the following paragraph about who eats whom in the Antarctic and draw a food chain that shows the feeding relationships in this habitat.
Don’t forget that your food chain must start with a producer!
Killer whales or orca’s range around Antarctica hunting for their food. One of the species that they eat are the Weddell Seal. Weddell seals are large mammals that stay in Antarctica all year round. One of the many things that they eat are squid. Squid are very fast hunters who often poison their prey. They feed on many different organisms including shrimp. Shrimp are small animals that live on the ocean floor. There are over 2,000 different species of shrimp all over the world. They are omnivores but phytoplankton makes up a large part of their diet.

3. Food chains and feeding types
Food chains always start with a producer.
If the producer is a plant it can be any part of the plant, such as the seeds, fruits, leaves or even dead leaves.
From looking at a food chain we can tell if an organism is a producer, a herbivore or a carnivore.
What are the feeding types of the animals in this food chain?
leaf
caterpillar
bird
cat

producers – make their own food;
primary consumers – eat producers;
secondary consumers – eat primary consumers;
tertiary consumers – eat secondary consumers.

8. What is a food web?
Most animals would get pretty fed up if they only ate one thing. Instead, they usually eat many different things and are involved in lots of different food chains.
plants  aphid  ladybird  blue tit  owl
plants  moth larva  blue tit  owl
plants  moth larva  spider  chiffchaff  owl
plants  vole  stoat
plants  vole  owl
These food chains can be put together in a food web,
which shows how the food chains are connected.
What would the food web look like for these food chains?
