Ecological Biology (1981)

The film explores the diverse ecosystems on Earth, highlighting the interactions between various organisms and their environments. It discusses the principles of ecology, including the distribution of organisms, energy flow, and the interdependence of species, using examples like muscles and starfish along coastlines and microscopic predators in laboratory settings. The importance of recycling materials in ecosystems is emphasized, noting that modern agriculture often disrupts these natural cycles. The video concludes by stressing that humans are integral to Earth’s life support system and our choices impact ecological balance.
