Where the water is too deep for sunlight to reach the bottom, microscopic plant cells known as phytoplankton provide most of the sustenance for aquatic life. Short Answer. Energy transfer between trophic levels tends to be of very low efficiency. Fungi (like mushrooms) are decomposers that decompose organic matter and consume that as their source of energy.

Net primary production 2. B) open ocean a. If the flow of energy in an arctic ecosystem goes through a simple food chain, perhaps involving humans, starting from phytoplankton to zooplankton to fish to seals to polar bears, In these places, micro-organisms collect in areas such as hydrothermal vents and cold seeps, where they get their energy from the metabolism of surrounding inorganic materials, such as the chemicals that seep up from the seafloor rather than from sunlight. Net primary productivity is the rate of carbon dioxide fixation by photosynthetic activity minus the fraction of carbon used for the maintenance and cellular respiration by the autotrophic planktonic microbes and the benthic plants.
