Exercise
Food Webs: Transfer of Carbon and Nitrogen
Dive into the intricate world of ecosystems by exploring food webs and understanding how carbon and nitrogen cycle through various organisms. In this engaging exercise, students will create their own food web diagrams, illustrating the flow of these essential elements and revealing the interconnectedness of life.
