If 50000 J energy available to primary producer, then energy available to tertiary consumer will be:

50J

The correct answer is Option (2) → 50J

If 50,000 J of energy is available to the primary producer, then each trophic level will receive approximately 10% of the energy from the level below it. Here’s how it would work:

1. Primary Producer: 50,000 J
2. Primary Consumer: 10% of 50,000 J = 5,000 J
3. Secondary Consumer: 10% of 5,000 J = 500 J
4. Tertiary Consumer: 10% of 500 J = 50 J

So, the energy available to the tertiary consumer would be: 50 J
