If the sun contributes 11382400 kj of energy and the producers were only able to assimilate 1% of that energy how many joules would they be able to use?

Primary producers are organisms belonging in an ecosystem that produces biomass from inorganic compounds within the environment. They are also called autotrophs and in almost all cases, these are organisms capable of photosynthesis. If they are only able to assimilate 1% of the energy given off by the sun, and the sun provides an energy amounting to 11,382,499 kJ of energy, then primary producers can utilize only 1,138,240 kJ of energy for its photosynthetic activities.

The correct answer will be option-A.

Explanation:

The gradualism and punctuated equilibrium are the mechanisms which explain the process of evolution of species through speciation or the formation of species.  

Both the concepts explain the rate of changes that take place in a population as the process of gradualism explains the slow rate of speciation while punctuated equilibrium explains the sudden rate of evolutionary changes taking place in any population.

Thus, option-A is the correct answer.
