rocks
because they feed on the little micro organisms and such at the bottom of the lake or pond. hope this helps. :)
In all probablilty there are not. I would assume that the base of an artificial pond would in all probablilty contain far less organisms than that of a well established lake.
At the bottom of a pond, you will typically find sediment, mud, rocks, plants, and sometimes small organisms such as insects or microorganisms. The specific composition can vary depending on the location and environmental conditions of the pond.
Every animal in the pond is part of the pond food chain. The animals at the top of the chain are large fish, and the animals at the bottom are bacteria and single-celled organisms.
Bottom waters of a pond refer to the water located at the lowest level of the pond, closer to the sediment or substrate. This water tends to be cooler, denser, and may have lower oxygen levels compared to the surface waters. Organisms that live in or interact with the bottom waters are adapted to these specific conditions.

Aquatic organisms that grow in the sediments at the bottom of a pond or lake are called benthic organisms. This group includes various species such as algae, bacteria, worms, and small invertebrates that play crucial roles in nutrient cycling and the overall health of the aquatic ecosystem. They often serve as a food source for higher trophic levels, contributing to the pond or lake's food web.

As the water mixes, minerals, plant matter, and othernutriens rise from the lake bottom to the surface. Calledlake turnover,this seasonal change refreshs the supply ofnutriens throughtout the lake.
Mostly photosynthesis, ingestion of de bris, providing energy as they are bottom of food chain
It's definitely the microorganisms, or if there are scavengers in your place.
Because the population of organisms is pond effect
