¿Qué es una cadena trófica?

The video explains how energy flows through living organisms via food chains, starting with producers that convert solar energy into sugars through photosynthesis. Herbivores consume plants, and carnivores eat herbivores, but energy is lost at each level. This is illustrated by a biomass pyramid, showing fewer organisms at higher levels. Scavengers and decomposers recycle energy and nutrients back into the environment. Ultimately, almost all energy originates from the Sun.
