Answer

Brief Explanations:

The deep - scattering layer is composed of large numbers of small organisms like fish, squid, and zooplankton. Their vertical migrations can be detected by depth recorders. A thermocline is a layer in the ocean where the temperature changes rapidly with depth and is not what the deep - scattering layer refers to. Moonlight has no direct relation to what is detected by depth recorders in the context of the deep - scattering layer.

Answer:

O large numbers of small organisms
