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)

(c)
The maximum energy is available at T1.
There is progressive decrease in the amount of energy accessible from 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 rest is passed to next generation. 100% effectiveness is not possible so some of energy is lost starting with one generation then onto the next.

Therefore option (C) is correct
