[@priyanshsingh8372]

@@SociallyshubhamMa'am CBSE has understood that we can't prepare 50% of our syllabus just in 2 months , thus it gave 2 extra months . But not able to understand that why our schools are not able to understand the same thing 😭.Can't they conduct the preboards in the last week of March or the first week of April . And the most deplorable thing is that the CBSE is not taking any kind of action . ICSE is better , it has strictly allowed it's school to conduct their preboards in the last week of March or the first week of April . It is really stressful and very badly impactful on the student's mind . 😓😓😓🙏🙏🙏

[@tanushreedhawan3263]

Bcz suppose kisi chhoti fish ne chemicals consume kr liye, toh aage jo badi fish hogi vo jab chhoti fish ko khaegi to 1 chhoti fish ki 10% energy hi use mil paegi....aur use aur energy chahiye hogi jiske liye vo aur aisi chhoti fishes khaegi. Aur as we know har chhoti fish ne thoda thoda chemical consume kiya to socho jo badi fish boht sari vesi chhoti fishes ko khaegi, uske andar kitna sara chemical concentration pohanch jaega...ab aage dekho next level, let's take a bigger fish, let's say a shark, to vo big fish ko khaegi....aur 1 big fish se sirf 10% energy hi milegi use.....to vo boht sari big fish khaegi...aur har fish me jo chemical concentration hoga vo add up ho k shark me chala jaega So is tarah se as we go up in the trophic level, energy decreases as per 10% law but at the same time we observe bio magnification, that is, the chemical concentration increases with each level Hope it's clear now
