This activity is designed to help pupils understand food webs.
Learning Objective: I understand what food webs represent, I can construct a food web
using various example components, I can use scientific vocabulary associated with food webs.
Learning Experiences: I can use my knowledge of the interactions and energy flow between
plants and animals in ecosystems, food chains and webs. I have contributed to the design or
conservation of a wildlife area. SCN 2-02a
A food web shows the relationship between all the different food chains within a particular
habitat.
The food web below shows a marine food web:
Killer Whale
Elephant Seal
Penguin
Leopard Seal
Cod
Squid
Krill
Phytoplankton
Zooplankton
All of the different parts of the food web are interconnected. If a change occurs in one part of the
web, it will impact upon the other organisms in the web. The arrows in the web show the direction
of the flow of energy from one part of the web to the next.
Get your pupils to design a food web for the animals below, and then answer the questions that
follow.
