Question

In a given food chain, suppose the amount of energy at fourth trophic level is 5kj, what will be the energy available at the producer level grass >> grasshopper >> frog>>snakes>>hawk

Answer 1

as the food chain starts it was zero as it increases it to convert to energy

Answer 2

It produces an amount of 5000KJ

Explanation:

• In a food chain when an energy passes from one level to another only 10% of the energy is consumed to the next level

• If in fourth level the energy is 5KJ as it passes from one energy level to another the energy reduces

• Then the energy at the third level will be 50KJ because of the food chain

• When it comes to the second level  500KJ of energy will be the energy unit of the food chain

• The producer will be full of energy and it is the highest producing energy level in the primary production level it produces an amount of 5000KJ
