Question

(a) Explain 10% Law in reference to the flow of energy across various Trophic Levels.
(b) Find out the amount of Energy available to Eagles in a Food Chain consisting of Carrots - rabbit - snake – eagle. Assume 1, 000 J of energy is available to Carrot plants from the Sun.​

Answer 1

Answer:

Food Chain-: It is a hierarchical and sequential tropic level system in which all the biotic organisms are connected to each other to get their source of food . Balancing the food chain is very essential for the existence of different forms of life on the earth.

Explanation:

Food chain is the sequential and hierarchical tropic level system.

There are 4 tropic levels :-

[Producers -> primary

consumers -> secondary

consumers -> tertiary

consumers -> Quarternary consumers ]

There can be either three or four tropic levels.

(a) At each tropic level 10% of energy is transferred from that tropic level to its next tropic level and the rest energy is consumed by that topic level itself. This is known as the 10% law. The transfer of energy at each tropic level is sequential.

(b) Here in the given example of food chain in the question,

Carrot -> Rabbit -> Snake -> Eagle.

Carrot has energy of 1,000J received from sun so now 10% of that energy would be transferred to its next tropic level so rabbit will get 100J, then again 10% of this energy is transferred so snake will be getting 10J and then finally eagle will get only 1J of energy.

Answer 2

Answers are as follows:-

{A} The 10% Law in reference to the flow of energy across various Trophic Levels suggests that the energy available at each successive trophic level is only 10 percent of the previous level. The green plants constituting the producer level capture only 1% of the solar energy and convert it into food energy.

{B}Given Food Chain: Carrots - Rabbit - Snake – Eagle. Here, Carrot plant represents the producer level. We know plants capture only 1% of the solar energy. Hence, the energy available to carrot will be 1% of 1,000 J that is 10 J.
