Net secondary production is the energy stored in biomass represented by growth and reproduction Assimilation consists of the total energy taken in and used for growth reproduction and respiration Production efficiency is thus the fraction of food energy that is not used for respiration This differs among organisms |

What is secondary production in an ecosystem?
- Secondary production in an ecosystem pertains to the production by con- sumers. Heterotrophic organisms use organic molecules as a source of both energy and carbon, and are fully dependent on carbon and energy fixated by autotrophs.
What are the primary producers of an ecosystem?
- The primary producers of an ecosystem trap the radiant energy of the sun and covert it into potential chemical energy. This trapped energy flows in the food chain from the producers to the top carnivores, decreasing at successive trophic levels.
Why is secondary production the ultimate measure of population'success'?
- Some consider secondary production the ultimate measure of population ‘success’ because it incorporates aspects of survivorship, individual growth rate, biomass, development time, and reproduction. Secondary production is often associated with the subfield of ecosystem ecology because it is a flux with dimensions of mass or energy area -2 time -1.
What are the basic processes of an ecosystem?
- Trophic (Food) Levels in Ecosystem Several fundamental processes take place within an ecosystem: assimilation, photosynthesis, consummation, decomposition, transformation (conversion).
