correctly and protect the environment.
Through this activity you will able to understand the atomic level
the process that plants use to
energy into chemical energy.

plants given to their correct place - in the empty boxes.
Step 3: When the chain is complete you can watch the food chain in action.
Step 4: Continue the activity by click on the next icon. Play and observe the
