CREATE A FOOD CHAIN
A food chain is a partial part of a food web. You will create a food chain
using the creatures from the previous page .
Remember you are drawing this food chain, you may use an app that
allows you to draw or complete it on a piece of paper.
• Draw one box at the top of the page. This box
is for the biggest predator in the food web.
• Draw three boxes across the middle of the
page.
• Draw two boxes across the bottom of the
page. These boxes are for the lowest plants or
animals in the food web.
The point of a food web is to display who eats who. Thinking about who eats
who in shark bay label each of the boxes how you believe the food chain may
work. Top predators go at the top of the food chain!
NB: Use a pencil because you may change where you put you organisms.
