The classroom resource provides a video that will describe the interactions between organisms in a food chain. There is also a short test that can be used to assess students' understanding. Students can use the information presented in this video to create their own model that shows the transfer of matter between organisms.
The test may be completed as a whole group or independently on student devices.
There is a printable available that includes a short synopsis of the video and definitions of the vocabulary words. This could be used as a notetaking sheet for students as they watch the video.
