Question

5.Consider the following food chain which occurs in a forest: Gnags -> Deer
- Lion
If 10000 J of solar energy is available to the grass, how much energy would
be available to the deer to transfer it to the lion? Where is maximum
biological magnification seen in the above given food chain?​

Answer 1

Answer:

10000 J of energy is available to the grass.

We know that plants use only 1% of the sunlight available to them to photosynthesize.

So, energy taken up by grass = 1% of 10000J = 100J

Now, according to 10% rule, deer will have 10% of the total energy of the grass.

So, deer will have 10% of 100J = 10J of energy.

Again, according to 10% rule, lion will have 10% of the total energy of the deer.

So, lion will have 10% of 10J = 1J of energy.

The maximum biomagnification is seen in the apex level of the food chain, that is, in lion.
