When those predators die, it is then up to the decomposers to hit the reset button on the food chain by harvesting nutrients that were passed from the producers to the consumers so they can be used again. Dr. Feller spends much of her time perched in mangrove trees or sitting among their gnarled thicketscounting, measuring, weighing, photographing and comparing the leaves and animals she finds.
