In the given Figure 15.1 the various trophic levels are shown in a pyramid. At which trophic level is maximum energy available?

(a) T4
(b) T2
(c) T1
(d) T3

Answers (1)

The maximum energy is available at T1.
There is a progressive decrease in the amount of energy accessible from the producer to higher trophic levels, i.e., T1> T2> T3>T4.
Starting from one level to another, some part of the energy is consumed and the rest is passed to the next generation. 100% effectiveness is not possible so some of the energy is lost starting with one generation and then onto the next.

Therefore option (C) is correct.
