Answer» We have given, 1/10 of the food eaten is turned into organism’s own body. ∴ The required fraction of the food eaten not available for the next level is 1 - 1/10 = (10-1)/10 [∵ L.C.M. of 1 and 10 is 10] = 9/10

Answer»

We have given, 1/10 of the food eaten is turned into organism’s own body.

∴ The required fraction of the food eaten not available for the next level is

1 - 1/10 = (10-1)/10

[∵ L.C.M. of 1 and 10 is 10]

= 9/10
