According to 10%law Grass receives 30,000J of energy from sun☀then primary consumer (rabbit) receives 3,000J energy from producers🌱 (grass) then secondary consumer (snake) receives 300J of energy from primary consumer and after then Tertiary consumer receives 30J energy from secondary consumer That's how this 10%law works

Mam In which rate the PPM will increase in different trophic levels in Bio Magnification??

[@THE_SUCCESS769]

it depends on how much toxins are present in the organism and how many organisms are eaten by organisms of next tropic level

Don't worry....there is no particular rate regarding this, it depends on the toxin quantity and consumer accumulation rate.

Answer : according to 10 percent law only ten percent energy is transferred from one level to another so as grass receives 30,000 energy from the sun so its ten percent will be transferred means rabbit will receive 3000J energy and snake will receive. 300J and eagle will receive only 30J energy . In short : 30000J - grass 3000J- rabbit 300J- snake 30J - eagle
