Ecosystem Dynamics and Energy Flow

Dr. Rudy Rosen introduces the Texas Aquatic Science curriculum, highlighting its development and funding sources. The lesson focuses on energy flow and communities in aquatic ecosystems, posing key questions about survival needs, population, habitat, and more. It also explores food webs and predator-prey relationships in various environments like ponds, estuaries, and the Gulf of Mexico.
