Antarctic food chain

The Antarctic food chain is an illustration of the food chain in the ocean in the form of food. How to make it quite young just by cooking rice colored in green as a representative of phytoplankton, rice with red coloring as zooplankton. Then add the cooked prawns, squid or fish. To eat it, you can add sauce as a complement.

Even lowly krill can live up to 10 years in the cold seas of Antarctica

Real Antarctic Krill

Green rice represents phytoplankton

Green rice (phytoplankton), brown rice (zooplankton) and shrimp (krill) on the spot

Add the top predator in this food chain, squid, you can use small fish instead

Lastly add extra rice and chili sauce to make it more edible for the main apex predator - you

Krill are crustaceans that live in the ocean and are essential to the Antarctic food web. These are herbivores that feed on phytoplankton (phyto - plants) as well as some smaller zooplankton (zoo - animals). It is itself a member of zooplankton as it moves with ocean currents rather than being able to actively swim against them (plankton definition). It uses a "basket" made of its forelegs to filter plankton from the water. It is very good at this.

Krill feed on a lot of phytoplankton that concentrates their food into much larger pieces of food - the krill themselves, which are then eaten by almost anything and everything that can be fished in Antarctic waters.


  • White rice
  • Green food coloring
  • Red food coloring
  • Whole prawn shell
  • Little squid

Cook rice using the absorption method where you add about half a cup of rice to three times the volume of water. Add green food coloring at the start of cooking according to the directions on the bottle. In this way, as the rice absorbs water and swells, it also absorbs the food coloring. Wash the starch when it is cooked.

Cook about a third of the rice you added the red dye to instead, you'll need to do this in a different pan to avoid messing up.

I bought a bag of ready-made frozen prawns and prepared raw little squid. Defrost some prawns and some squid. Cook the squid by frying them in a shallow frying pan with a little oil for a few minutes on each side, then remove and pat dry and remove excess oil with a kitchen towel.

Assemble a food chain on a suitable background. I couldn't find anything blue to represent the sea, so I settled for a tray I made out of foil with folded edges. You can use a blue plate or even a cleaned blue tray if you have one to represent the ocean.

Spread the green rice around, it represents the phytoplankton, sprinkle with a little brown rice which represents the zooplankton. Now position your shrimp (playing the role of krill) and squid, (guest star as himself). You can use fish as a substitute for, or alternatively, any available squid and shrimp.

I thought it needed some sauce to go with it as it was a bit boring and opted for the sweet chili because I like it. It doesn't represent much but means that your food chain becomes more than food.

Sweet chili sauce - from a bottle or:

  • 1 cup water
  • 1 cup rice wine vinegar
  • 1/2 cup sugar
  • 1 teaspoon chopped or grated fresh ginger
  • 1/2 teaspoon garlic, chopped
  • 1 teaspoon of cayenne pepper, chopped
  • 1 teaspoon soy sauce
  • 1 tsp cornstarch/corn flour

Add water, vinegar and sugar to a saucepan and bring to a boil, add ginger, garlic, chili and tomato sauce and simmer for 5 minutes. Mix the cornstarch/cornstarch with a little water and add at the end to thicken the sauce. Most things vary according to taste, sugar, chili, garlic and tomato sauce.

When you follow a food chain, you get fewer organisms, although usually larger ones.
