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.
