D) Predators have short life spans and short reproductive periods. C) 4C Which of the following best describes the fate of the unconverted energy? Are bacteria heterotrophic or autotrophic? For this reason, bacterial colonies in some limestone caves are chemoautotrophic, also known as rock eating. These bacteria, like those in the ocean depths, get their necessary nourishment from the nitrogen, sulfur or iron compounds found in or on the surface of rocks that have been carried there by water seeping through the porous surface. A) It is undigested and winds up in the feces and is not passed on to higher trophic levels. They do this through the process of photosynthesis. For example, if 1,000 kilocalories of energy are present at the primary producer level, one-tenth of this energy (about 100 kilocalories) is passed to the primary consumers in the next level. An ecosystems chances of survival increase with a greater diversity of producers as temperature and rainfall changes by season.
