Given that:
Primary producer biomass: 10,000 kg
Primary producer energy content: 1,000,000 kcal

According to the 10 percent law, approximately 10 percent of the energy is transferred from one trophic level to the next. So, we need to calculate 10 percent of the energy at the primary producer level.

10 percent of 1,000,000 kcal = (10/100) * 1,000,000 kcal = 100,000 kcal

Hence, the correct answer is Option 3 that is 100 kcal.
