This week on The Naturalist, Bernie Wides welcomes back guests from The Discovery Room at the Museum of Natural History. On this program, they explore the properties of some of the smallest critters in the ocean – plankton! Tune in to learn why plankton are so dangerous and essential to human life at the same time. Find out more about photosynthesis, the food chain and industrial uses of diatomes on an information packed episode of The Naturalist. This episode was sponsored by S. Wallace Edwards & Sons.
