'Food chains and webs'

05:33 Mar 15, 2021
'This video is about food chains and webs and is for Key Stage Three pupils (pupils in Years 7 & 8). The video introduces food chains and the key words associated with them (producer, consumer e.t.c). I discuss why food chains are normally not longer than 4 or 5 organisms. At the end, I discuss the interactions of animals in food webs.'
