How Microscopic Hunters Get Their Lunch

The video explores how living organisms obtain energy and food, focusing on heterotrophic single-celled eukaryotes. It describes three main feeding strategies: filter feeding, raptorial feeding, and diffusion feeding. Filter feeders use cilia to create currents that bring food to them, while raptorial feeders hunt and capture prey using specialized structures. Diffusion feeders rely on prey making contact with them. The video highlights the diversity and complexity of feeding mechanisms in microorganisms, illustrating the constant and brutal nature of predation in the microcosmos.
