Understanding Metabolism and Energy

The video discusses how various living organisms, such as baseball players, birds, and flowers, use energy for their activities. It explains that food is the primary source of energy for cells, which convert it into other forms to perform functions like growth, repair, and waste elimination. The concept of metabolism, encompassing all chemical activities in living organisms, is introduced. Finally, the video hints at how certain cells harness energy from the sun for metabolic processes.
