What do you think happens to all the nutrients that enter the watershed through the excrement of aquatic organisms?

Check out this KQED resource and meet the underwater characters that make a living cycling nutrients through the watershed. Learn how the physical, chemical, and biological systems within watersheds work together to create a continuum of resilient, interconnected ecosystems. Watch the food chains spiral nutrients in and out of the river basin in a vast web of interactions.
