Food Chains and Food Webs Explained | Energy Flow in Ecosystems

This video explains how energy moves through ecosystems by comparing simple food chains with complex food webs. Learn how interconnected feeding relationships create stability, allow organisms to adapt, and shape biodiversity through indirect effects and trophic cascades. The lesson also explores keystone species, multiple energy pathways, and why ecosystems function as dynamic energy networks rather than linear systems. Perfect for biology and ecology students studying energy flow and ecosystem interactions. Check out my TpT Store: https://www.teacherspayteachers.com/s...
