- Invertebrates enhance the rate of decomposition of leaf litter by increasing the surface area by consuming pieces of the leaves. adding their fecal material to the leaves on the forest floor. burying the leaves within the upper soil layers. adding their digestive enzymes to the leaves.In herbivory, an individual of one species eats part ofa plant or other primary producer, such as a cariboueating a lichenCrab Sea Slug Algae on Eelgrass Eelgrass Figure 1. Partial food chain in eelgrass habitats 1. Sea otters are native to the western coast of North America. Between 1750 and 1850, hunting had reduced the population from hundreds of thousands to only one thousand individuals. In the early 1900s, a small population of sea otters was discovered in Elkhorn Slough, an estuary in central California near a large human population center. The otters were then protected by the international fur seal treaty, which banned sea otter hunting. The sea otter population has rebounded to nearly three thousand individuals today. Otters live in kelp forests and eelgrass beds and feed on crabs and shellfish (Figure 1). Most herbivores in the habitat eat algae that grows on the eelgrass and not the eelgrass itself. If there is too much algae, the eelgrass does not receive enough light for photosynthesis. As the otter population has increased, the eelgrass habitat has increased. Recently, however, scientists…
