A food web describes the flow of energy and nutrients through an ecosystem, ... Organisms can be organized into trophic levels: primary producer, primary ... In both food webs and food chains, arrows point from an organism that is consumed to ... of trophic energy transfers, the amount of energyremaining in the food chain ...

Answer and explanation;

-The energy available to the next level is 10% of the previous level.

-When an organism consumes food from the previous trophic level, some of that energy is used for metabolism, growth, and tissue repair. The amount of energy obtained from the previous level is not all converted to biomass. Roughly ten percent of it is available for consumption.

-The amount of usable energy stored in the biomass of organisms is decreased because most of the energy taken in by consumers is used for movement or released as body heat. The percentage passed on is usually taken as 10%, although this is a very generalized average, and different ecosystems have varying efficiencies.
