Indicate the flow of energy in an ecosystem

1.	Indicate the flow of energy in an ecosystem
Answer» Only 50% of the incident solar radiation is photosynthetically active radiation. Out of this plants capture about 2 to 10% of the energy. This small fraction of energy is what sustains life on the earth. The energy flows from produces (green plants) to consumers or to detritus. The flow of energy follows 10% rule. As per this rule 90% of the energy is spent in metabolic activities by an organism and only 10% is available for the next component of the food chain.Producers{tex} \\to {/tex}Primary consumers {tex} \\to {/tex}Secondary consumers {tex} \\to {/tex}Tertiary consumersBecause of this 10% rule a food chain can have limited number of levels. Numerically also the number of organisms in a particular level will be less than that in the previous level
