Question

in a food chain, 1200 kJ of energy had
fallen on the green parts of a plant, then
the difference in the amount of energies
that are gained by primary and
secondary consumers is ​

Answer 1

Answer:

according to the 10 percent law, only 10% of the energy is transferred to each trophic level from its lower trophic level. If 1200 joules of energy is available to the producer, then only 120 joules of energy will be available to the primary consumer and only 120 joules of energy will be available to the secondary consumer. The energy available with the tertiary consumer will be 12 joules of energy.

explanation:

energy available to plant = 1200J

energy available to sheep

= 1200×10/100

= 120J

energy available to man

= 120×10/100

= 12J

Answer 2

Answer:

Energy available to plant= 1200J

goat(secondary)=120J

man(tertiary)= 12J

Explanation:

The amount of energy in a food chain decreases with each trophic level. This indicates that the quantity of energy received by the plant from the sun differs from the amount received by the tertiary consumer (or final trophic level) of the food chain. This occurs as a result of the use of energy at each level.

If 1200J is present for the producer then according to this 10 percent law for the secondary(goat) consumer the energy left out will be 120J and for the tertiary(man) it will be 12J.
