When plants and animals die, they become food for these decomposers. Whereas the sulfur-loving bacteria often found around whale carcasses and thermal vents mentioned above create their own energy via a process known as chemosynthesis, most bacterial species in the ocean are true heterotrophic decomposers. Dead animals, plants and insects will remain in their forms and never dissolve in soil. Since no photosynthesis can take place, deep ocean ecosystems have low levels of organic matter and mostly rely on influx of organic matter from shallower waters. While bacteria are restricted to growing and feeding on the exposed surfaces of organic matter, fungi can use their hyphae to penetrate larger pieces of organic matter, below the surface. The ones that live on dead materials help break them down into nutrients which are returned to the soil. Organic waste: Waste created by or from a once-living organism. How Are Mushrooms Decomposers?
