Question

In which zone of the lake does the light cannot penetrate?

(a) Littoral

(b) Limnetic

(c) Photic

(d) Benthic

I had been asked this question during an interview for a job.

I would like to ask this question from Organisms and Populations in chapter Organisms and Populations of Biology – Class 12

Answer 1

Right choice is (d) Benthic

The explanation: The light cannot penetrate the bottom zone of the lake called benthic. Littoral is the shallow, coastal region. Limnetic is very deep and has open water while photic is the upper part of limnetic. Light can pass through all three zones except benthic.
