Answer:

30 units of energy will be available to primary predators.

Step-by-step explanation:

Using 10 % law i.e at each step 10 % of energy is transferred to the next trophic level at the rest of either consumed or lost to environment..

so plants have = 3000 units

herbivores = 10% of 3000 = 10/100 × 3000

= 300 units

so primary predators will have = 10% of 300

= 10/100 × 300 = 30 units
