Solution

As per the question

The quantity of food eaten which turned into organism's own body and is available for next level of the consumer = $\frac{1}{10}$ of the total food
Now, the quantity of food eaten which is not available for the next level = $1 - \frac{1}{10} = \frac{1 \times 10}{1 \times 10} - \frac{1 \times 1}{10 \times 1} = \frac{10}{10} - \frac{1}{10} = \frac{10 - 1}{10} = \frac{9}{10}$
Hence, $\frac{9}{10}$ th of the food eaten is not available for the next level.
