Question

Arrange the given organisms into a food chain. Frogs, Plants, snakes, hawks, insects

a. Which organism will receive maximum amount of energy. Why?
b. Which organism will receive maximum amount of toxic chemicals. Why? If the
member receives 30 J of energy, calculate the energy that would have been available
for the previous trophic levels. state the law used in the calculation​

Answer 1

Answer:

Plants <Insects<Frogs<Snakes<Hawks

A).Insects will receive maximum energy becoz as per 10% energy law , only 10% of the energy is transferred to next trophic level.

B). Hawks will receive maximum amount of toxic chemicals coz chemicals will keep on accumulating from the T1 to the last Trophic level.

If Hawks receive 30J of energy then , energy available for the previous trophic levels will be :

Snake 300 J

Frog 3000J

Insects 30000J

The law used is 10% energy law .

Answer 2

Answer:

Explanation:

Plants, insects, frog, snake, hawk.

a) since plants themselves are the producers. So when it comes to receiving of energy, insects will get maximum Lindeman's 10% energy rule,the subsequent level will get lesser energy.

b) the organisms at last trophic level will get maximum toxic substances, which is known as bio magnification
