Los fundamentos de la ecología: cadena alimenticia y redes de alimentación

The video explains how diagrams are used to illustrate energy transfer in ecosystems, focusing on producers like algae that create food from the Sun's energy. It describes a simple food chain involving the Sun, algae, and marine iguana, and contrasts it with more complex feeding nets found in ecosystems like the Everglades. The roles of predators and prey are discussed, highlighting the interconnectedness of living organisms in food webs.
