"Ocean food webs" multimedia activity

This multimedia activity was conceived as a complementary class activity for the lesson plan provided in the OCE guidebook The climate in our hands - Ocean and Cryosphere.

Through this activity, the students can learn the names and predatory relationships of multiple animal and plant species belonging to six different marine food webs, and living in distinct world regions: the Arctic, the Antarctic, kelp forests, mangroves, the North Sea and coral reefs.

The food webs proposed are not all of the same complexity: it is up to you to choose the most adapted to your students, taking into account their knowledge and skills, and also their local context!


  • To start playing, click on the corresponding image, for each of the marine food webs:

Teacher's notes:

  • A "back door" allows you to proceed to step 2 of the animation without completing step 1. To do this, go to the menu and move the mouse under the text "Credits": the word "Backdoor" then appears .
  • The solution of step 2 of the animation (as well as an "unplugged" version, based on card games) is given in the teacher handbook "The climate in our hands - ocean and cryosphere" (cf. lesson D2, pages 102 and following).
