The bacteria section uses compelling microscopy of living bacteria to examine their structure, physiology, behavior, and the vital roles these microbes play in the biosphere, including oxygen production (cyanobacteria), decomposition, nitrogen fixation, and as parasites as well as helpful symbionts.

The term algae is a catchall for several evolutionary lines of photosynthetic organisms: dinoflagellates: red algae (plastids with chlorophyll A); diatoms, yellow-brown algae and brown algae (chlorophylls A and C); and green algae (chlorophylls A and B). This program explores the diversity, structure, ecological roles and modern classification of these vital primary producers.

• The Living Humous – studies the living component of soil, where dead organic material is broken down through the efforts of decomposer bacteria, sow bugs, millipedes, centipedes, and fungi.
• The Rotting Log – looks at how dead wood returns to the soil with the help of termites and the symbiotic microorganisms living in the termite gut.

The term "protist" covers a wide range of microscopic organisms formerly clumped into "Kingdom Protista." New molecular analyses show that the protistan lines of evolution go so far back in time they can be considered as different kingdoms of life.
