Understanding Heterotrophs

The video explores the concept of heterotrophs, organisms that obtain energy by consuming other organisms. It introduces different types of heterotrophs: carnivores, omnivores, herbivores, and decomposers, explaining their roles and examples. The energy pyramid is discussed, highlighting the hierarchy of consumers from primary to tertiary. The video concludes with a message on kindness.
