Your noticings:
After watching the videos above, why do you think kelp is so important to our oceans?
List at least 5 noticings, (new things you learnt) using the heading: "Why kelp is a hero of the ocean".

Did you know...
Food Chains and Food Webs are not the same thing!
Food chains show how energy is passed from one living thing to another. It follows a strict line from smallest to biggest and it always begins with the sun.
Food webs have small food chains in them. They show lots of different ways that energy can be passed between food chains. It does not follow a strict line.
Watch this video to help you understand more about the differences between food chains and food webs.
Food Web

Under the heading "Food Chains and Food Webs" describe in your own words how food chains and food webs are different.
