Question

what is the source of food for the organisms that live in deep water of the pond or lake​

Answer 1

Answer:

pond is an area filled with water, either natural or artificial, that is smaller than a lake.[1] It may arise naturally in floodplains as part of a river system, or be a somewhat isolated depression (such as a kettle, vernal pool, or prairie pothole). It may contain shallow water with aquatic plants and animals.[2]
