Question

Only about 10 percent of the energy in an organism is passed on to the next level of a food chain. Look at this food chain: grass → rabbit → hawk

What percentage of the energy stored by the grass is passed on to the hawk?

Answer 1

1%

Answer 2

I agree, it's 1%.

Answer 3

10% of the energy in the grass is passed on to the rabbit. So you only have 10% left in the rabbit. 10% of the energy in the rabbit is passed on to the hawk and 10% of 10 is 1%
