In the given scenario, the plant, as a producer, captures 1,000 units of energy from sunlight. Since only 10% of energy is transferred between trophic levels, the primary consumers would receive:
1,000 units of energy × 10% = 100 units of energy.
Therefore, the correct response is:
100 units of energy.
