1 Make a table, like the one shown below, to show all the organisms in the food web. Some organisms may appear in more than one column. Producers Consumers Herbivores Omnivores Predators Top predators 2 A food web is like a flow diagram. It shows how energy is transferred between the plants and animals in a habitat. Where does this energy originally come from? 3 Write down the longest food chain in the food web. 4 Write down the shortest food chain in the food web. 5 Humans eat Antarctic toothfish. Write out a food chain that includes this fish and humans. 6 Name three organisms that are in competition with one another. 7 Krill are tiny creatures that look a bit like miniature shrimps. They grow best under the ice that forms on the sea in the Antarctic winter. Global warming means that less of this ice is forming. What effect will this have on the food web?
