From Sunlight to Snack: The Energy Journey in the Animal Kingdom

The video tutorial explains the concept of consumers, organisms that obtain energy by consuming other living things. It covers the process of digestion and metabolism, highlighting how nutrients are broken down and converted into energy. The tutorial delves into chemical respiration, where glucose and oxygen react to release energy, producing carbon dioxide as a byproduct. It also discusses metabolic rates, noting variations among different organisms and life stages. Finally, the video describes food chains, illustrating how energy is transferred from plants to animals and further up the chain.
