Question

Which of the following is a conduit for energy transfer across trophic levels((a)mutualism (b)parasitism(c)photocooperation(d)predation

Answer 1

Answer:

Conduit for energy transfer across trophic level is performed by

PREDATION.

It is a type of positive-negative relationship between 2 types of organisms.

Let us consider an example:

A zebra receives energy by eating grass.

Now, a lion preys on the zebra and eats it. The lion now receives energy from the flesh of the zebra.

So, energy is being transferred from one trophic to another trophic level.

Another point to note is that:

The transfer of energy across trophic level follows 10% Law, i.e. only 10% of the energy of the lower trophic level is transferred to the higher trophic level.

Answer 2

Answer:

A zebra receives energy by eating grass. Now, a lion preys on the zebra and eats it. The lion now receives energy from the flesh of the zebra. So, energy is being transferred from one trophic to another trophic level.
