Invertebrates and fish that eat dead organic matter will be most abundant in the<u> benthic zone of freshwater lakes.</u>
In a marine water body, the most lowest zone in terms of ecology is called benthic zone. It name comes from the Greek letter βένθος which means 'depths'.
In this zone, sediments lay down at floor of the sea and provide essential nutrients and minerals to the organisms living in this zone.
Benthic zone, also referred to as ecological zone, possesses peculiar characteristics such as high pressure and low temperature.
The sediments of this zone recycle the nutrients and help in the survival of aquatic organisms.
