How to Create a Marine Food Web

A marine food web shows how the fish, plants and other creatures living in the ocean interact with one another as consumers and producers. It is the same as several connected food chains from the same environment. Producers in the food web make their own energy, such as algae and sea plants. Consumers eat producers or other consumers. Consumers include plant-eating fish and fish-eating sharks. Put together a food web with arrows indicating the links between organisms to help your understanding of the relationships between the living creatures in the seas.

Things You'll Need

Paper
Markers, pencils or crayons

Instructions

- 1
  Draw pictures of sea animals and plants on a piece of paper. For instance, you might have a drawing of a shark, a fish, a seal, seaweed and coral.
- 2
  Draw an arrow from each picture pointing to another creature that eats it. Some pictures will have more than one arrow pointing away from them or to them. For instance, the fish would have an arrow pointing at it, leading away from the seaweed or coral. Arrows pointing to the shark and seal would start at the fish.
- 3
  Label the pictures on the food web that do not have arrows pointing at them as producers, such as the seaweed and coral.
- 4
  Mark organisms with arrows leading to them as consumers, since they eat other plants or animals.
