Answer 1

1000 Joules


Hope answer was usefull..✌

Answer 2

The number of steps of each organism from the start of the food chain is termed as a trophic level. Plants are on the first step of the trophic level, herbivores in the second and it finishes with apex predators. Only 10% of the energy passes from one trophic level to another.

First trophic level= 10,000 J

According to 10 % law,

Only 10 % of a particular trophic level is available to the next level.

So for the 2nd trophic level the energy available will be:

10 % of 10,000

10/100 x 10000 = 1000 J
